Modified Filtering For Asynchronous Inputs

View page
US Patent:
6724845, Apr 20, 2004
Filed:
Aug 16, 2000
Appl. No.:
09/640128
Inventors:
Debarag Narayan Banerjee - Milpitas CA
Assignee:
Koninklijke Philips Electronics N.V. - Eindhoven
International Classification:
H04B 110
US Classification:
375350, 375285, 370342
Abstract:
For use in a digital signal processing system, a filter implementation factors in the time difference between consecutive searches for the same signal and modifies the filter depending on the time-arrival differences of consecutive search results. An example application to which the invention is particularly well adapted is in a mobile receiver for a cellular radiotelephone communications system. In accordance with the present invention, after determining a relative arrival time of data sample sets in the stream of data samples, the mobile station includes a receiver arrangement configured to filter a stream of data samples arriving at irregular intervals, to provide a relative arrival time of data sample sets in the stream of data samples, and in response to determining the relative arrival time, to filter the data sample sets using value assignments that are exponentially weighted for the data sample sets. The data sample sets are weighted more than data sample sets arriving early. In a more specific implementation, the receiver arrangement searches the data sample sets for a signal strength signal, and filters the data sample sets based on time-arrival differences of consecutive search results.

Pilot-Signal Searching With Decimation Reordering

View page
US Patent:
6771622, Aug 3, 2004
Filed:
Nov 17, 2000
Appl. No.:
09/715306
Inventors:
Debarag N. Banerjee - Milpitas CA
Assignee:
Koninklijke Philips Electronics N.V. - Eindhoven
International Classification:
H04Q 700
US Classification:
370331, 370335, 370342, 370441, 455436, 455502, 375145, 375149, 375150
Abstract:
An example application of the invention is directed to a mobile receiver searching pilot signals in a CDMA-based radiotelephone communications system. The receiver processes received pilot signals by first decimating those pilot signals that have a search window length that is greater than a threshold number of chips, into a plurality of sub-windows. The other pilot signals and the sub-windows are then searched using a common prioritization criteria. More specific implementations of this approach permit each search of this type to take a fixed amount of time, thereby making scheduling calculations easy to implement. Moreover, such implementations provide for all pilots to be searched equally often irrespective of window sizes, and for less likely candidates for idle handoff (pilots with longer window sizes) not to be given precedence over more likely idle handoff candidates. Also, as search results are accumulated, the amount of unsearched PN space within a window decreases, thereby decreasing the probability of finding a strong pilot and increasing the ability for more intelligent scheduling.

Data Throughput Over Lossy Communication Links

View page
US Patent:
7061856, Jun 13, 2006
Filed:
Feb 5, 2002
Appl. No.:
10/071557
Inventors:
Debarag N. Banerjee - Milpitas CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Stanford CA
International Classification:
H04L 12/56
US Classification:
370216, 370349
Abstract:
In a heterogeneous data network including both wired and wireless/lossy links, a transport protocol method implemented at the wireless host is fully compatible with existing wired networks and wireless gateways, and requires no modification to transport protocols at existing wired hosts. The wireless host calculates a temperament parameter [] characterizing the error-proneness of the data connection and uses this parameter to determine whether error-induced losses or congestion-losses dominate the data connection [. If congestion-losses dominate the data connection, then the host uses a standard technique for acknowledging data packets []. If, on the other hand, error-induced losses dominate the connection, the host uses a modified technique for acknowledging data packets []. According to this modified technique, the wireless host sends a plurality of non-duplicate acknowledgements of a single packet whenever a packet is received after an out-of-order packet is received. By acknowledging distinct fragments of the packet, rather than identical (i. e.

Estimating Eb/Nt In A Cdma System Using Power Control Bits

View page
US Patent:
7228146, Jun 5, 2007
Filed:
Jun 26, 2001
Appl. No.:
09/891798
Inventors:
Debarag Banerjee - Milpitas CA, US
Assignee:
NXP B.V. - Eindhoven
International Classification:
H04Q 7/20
US Classification:
455522, 455 69, 4552261, 370318
Abstract:
A portable communication device including a power control system which estimates E/Nby determining the variance of the noise components of PCBs that are received on the fundamental traffic channel. The power control system includes a demodulator for demodulating a BPSK modulated (or PAM) first signal from a base station, a noise variance calculation circuit that samples the perpendicular noise component of the demodulated signal to determine a noise variance, a power estimation circuit that measures the power of the demodulated signal and provides an estimate of the power of the first signal by eliminating the noise variance from the demodulated signal, and a comparator that compares the ratio of the power estimate and the noise variance to a threshold. The comparator output is a power up or power down signal to the base station.

Method And Apparatus For Generation Of Downlink Scrambling Code In Wideband Cdma Mobile Devices

View page
US Patent:
7286589, Oct 23, 2007
Filed:
Aug 29, 2003
Appl. No.:
10/651848
Inventors:
Karim Nassiri Toussi - Belmont CA, US
Debarag Banerjee - Sunnyvale CA, US
Gokhan Cosgul - San Jose CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
H04B 1/00
US Classification:
375130, 375147, 375342, 708252
Abstract:
An initialization method is performed to initialize the states for producing downlink scrambling code for a wideband code division multiple access (WCDMA) mobile device. The initialization method uses an auxiliary linear feedback shift register (x-LFSR) advance the x-initial state to a new initial state that corresponds to a selected downlink scrambling code. The new initial state allows the remaining masks used for generating the downlink scrambling code to be fixed. Memory required to produce the downlink scrambling codes is therefore reduced, as it is no longer dedicated to storing the sets of masks corresponding to each of the possible downlink scrambling codes.

System And Method For Channel Estimation In A Radio Frequency Receiver

View page
US Patent:
7286593, Oct 23, 2007
Filed:
Jul 15, 2002
Appl. No.:
10/195234
Inventors:
Debarag N. Banerjee - Sunnyvale CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
H04B 1/00
US Classification:
375148, 375142, 375152
Abstract:
A channel estimator for determining channel weighting coefficients for a finger of the RAKE receiver. The channel estimator comprises: 1) a first correlator for receiving a first pilot channel signal and correlating the first pilot channel signal with a first pilot channel chip pattern associated with the first pilot channel signal to produce an output comprising a first pilot channel symbol sequence; and 2) a first channel estimation filter capable of receiving the first pilot channel symbol sequence and generating first channel weighting coefficients. The first channel estimation filter minimizes the mean squared error of the channel estimate in the first channel weighting coefficients caused by additive noise and Doppler effects, wherein the mean squared error is minimized across a range of Doppler frequencies from 0 Hz up to a predetermined maximum Doppler frequency.

Apparatus And Method For Detecting Downlink Transmit Diversity At A Mobile Device

View page
US Patent:
7324617, Jan 29, 2008
Filed:
Mar 24, 2003
Appl. No.:
10/395992
Inventors:
Debarag Narayan Banerjee - Sunnyvale CA, US
Pascal Gilles Renucci - Sunnyvale CA, US
Karim Nassiri Toussi - Belmont CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
H04B 7/10
US Classification:
375347
Abstract:
A mobile device detects downlink transmit diversity. Slot and frame timing knowledge and a downlink scrambling code are applied to pilot and synch channels of the signal. An algorithm suited for the diversity case and an algorithm suited for the non-diversity case are utilized. The output of the diversity algorithm is compared to the output of the non-diversity algorithm. The output yielding the highest energy determines whether downlink transmit diversity is applied. The detection algorithms used in both the diversity and non-diversity cases use phasors to indicate the phase difference between two channels. This phase difference is the basis for determining diversity usage.

Method Of Optimizing Wireless Communication Links Using Stored Channel Characteristics Of Different Locations

View page
US Patent:
7333774, Feb 19, 2008
Filed:
Oct 7, 2004
Appl. No.:
10/962201
Inventors:
Debarag N. Banerjee - Sunnyvale CA, US
Arogyaswami J. Paulraj - Stanford CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
International Classification:
H04B 17/00
H04Q 7/20
US Classification:
455 6711, 4554561
Abstract:
Techniques for location-assisted wireless communication use real-time location(s) of wireless transceiver(s) together with stored location-indexed channel information to improve communication over a wireless channel between the transceiver(s). The stored channel information includes channel characteristics (e. g. , average power, angle-of-arrival, and time delay of multipath components) that are substantially constant in time but vary gradually as a function of location. Current transceiver location(s) are obtained and used to retrieve stored channel characteristics corresponding to the location(s). The channel information may be used at either or both transceiver(s) to improve reception and/or transmission of signals propagating over the wireless channel. For example, reception may be improved by using path angle information to perform spatially structured reception, or using path delay information to perform temporally structured reception, e. g. , to assign fingers to multipath components in a RAKE receiver and/or to track time delays of multipath components.
