Method And Apparatus For Achieving Data Rate Variability In Orthogonal Spread Spectrum Communication Systems

View page
US Patent:
6366588, Apr 2, 2002
Filed:
Feb 27, 1998
Appl. No.:
09/032166
Inventors:
Michael James Gans - Holmdel NJ
Laurence Eugene Mailaender - Hoboken NJ
Yu Shuan Yeh - Freehold NJ
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H04J 316
US Classification:
370468, 370206, 370320, 370335, 370342, 375240, 375261, 375268
Abstract:
A CDMA communication system is disclosed offering a near continuum of data rates up to a maximum rate. The disclosed CDMA communication system increases the data rate variability, without disturbing the orthogonality between users. An increased number of data rates is obtained by time multiplexing the data rates achievable with conventional CDMA systems to provide additional data rates for various multimedia applications. If a user is assigned a specific orthogonal code sequence, such as a Walsh sequence, which permits a maximum data rate, nR, with conventional systems, the user can obtain additional desired data rates up to the maximum rate nR, by time multiplexing the specific orthogonal code set. Desired bit rates are achievable for applications requiring bit rates that are not an integer multiple of the rates provided by conventional techniques. A fundamental rate of R or âfat pipeâ rates of powers-of-two multiples of the fundamental rate can be achieved in a conventional manner.

Code Division Multiple Access Communication With Enhanced Multipath Diversity

View page
US Patent:
6373832, Apr 16, 2002
Filed:
Jul 2, 1998
Appl. No.:
09/108775
Inventors:
Howard C. Huang - Hoboken NJ
Laurence Eugene Mailaender - Hoboken NJ
Giovanni Vannucci - Middletown Township Monmouth County NJ
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H04B 7216
US Classification:
370342, 375267, 455 69, 455101
Abstract:
A system, a transceiver, and methods for code division multiple access (CDMA) communication. The system includes first and second code division multiple access transceivers. The first code division multiple access transceiver has a plurality antennas disposed to provide transmission via a plurality of paths and the second code division multiple access transceiver has a rake arrangement for processing a plurality of signals received at the rake arrangement with differing delays or other characteristics. A driving arrangement is provided for causing the first code division multiple access transceiver to use a relative few, e. g. , one, of the plurality of antennas. When, however, an indication is obtained that an adequate number of resolvable signals are likely not received at the rake arrangement of the second transceiver, a circuit switches the driving arrangement to cause the first transceiver to use more of the plurality of antennas. In one implementation, the second transceiver sends a feedback signal indicating the number of useful signals being received and the first transceiver responds to the feedback signal by selecting and using a desirable number of transmit antennas. In an implementation suitable for a time-division duplexing (TDD) communication system, the first transceiver obtains the indication by inference from the fact that it is not receiving an adequate plurality of resolvable signals from the second transceiver.

Method And Apparatus For Enabling Transmission Of Variable Length Encoded Data In A Low Signal To Noise Ratio Environment

View page
US Patent:
6563879, May 13, 2003
Filed:
May 17, 1999
Appl. No.:
09/312711
Inventors:
Erik E. Anderlind - Parsippany NJ
Laurence Eugene Mailaender - Hoboken NJ
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H03M 730
US Classification:
375253
Abstract:
In order to transmit variable length encoded data in low signal to noise ratio environments, a first data pattern is added to a beginning portion of encoded data to signify a beginning of the encoded data. Further, a second data pattern is added to end portion of the encoded data to signify and end of the encoded data. Additionally, since the encoded data may naturally include the second data pattern and thereby mistakenly indicate an end of the encoded data, the encoded data is first checked for such a pattern. If the pattern is found within the encoded data, a new pattern is substituted therefore. In order to counter errors, patterns similar to the first data pattern are also substituted with new patterns. As such, a variable length encoded data can be transmitted in a low signal to noise ratio environment, and can thereafter be easily decoded.

Method And Apparatus For Determining An Inverse Square Root Of A Given Positive-Definite Hermitian Matrix

View page
US Patent:
7200631, Apr 3, 2007
Filed:
Jan 10, 2003
Appl. No.:
10/340575
Inventors:
Laurence Eugene Mailaender - New York NY, US
Jack Salz - Fair Haven NJ, US
Sivarama Krishnan Venkatesan - Secaucus NJ, US
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
G06F 7/32
G06F 7/38
US Classification:
708520, 708605
Abstract:
Generally, a method and apparatus are provided for computing a matrix inverse square root of a given positive-definite Hermitian matrix, K. The disclosed technique for computing an inverse square root of a matrix may be implemented, for example, by the noise whitener of a MIMO receiver. Conventional noise whitening algorithms whiten a non-white vector, X, by applying a matrix, Q, to X, such that the resulting vector, Y, equal to QX, is a white vector. Thus, the noise whitening algorithms attempt to identify a matrix, Q, that when multiplied by the non-white vector, will convert the vector to a white vector. The disclosed iterative algorithm determines the matrix, Q, given the covariance matrix, K. The disclosed matrix inverse square root determination process initially establishes an initial matrix, Q, by multiplying an identity matrix by a scalar value and then continues to iterate and compute another value of the matrix, Q, until a convergence threshold is satisfied. The disclosed iterative algorithm only requires multiplication and addition operations and allows incremental updates when the covariance matrix, K, changes.

Signal Detection By A Receiver In A Multiple Antenna Time-Dispersive System

View page
US Patent:
7359466, Apr 15, 2008
Filed:
Aug 24, 2001
Appl. No.:
09/938453
Inventors:
Howard C Huang - New York NY, US
Laurence Eugene Mailaender - New York NY, US
Magnus Sandell - Swindon, GB
Harish Viswanathan - Basking Ridge NJ, US
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
H04B 1/10
US Classification:
375349, 375345, 375350, 375232
Abstract:
In a MIMO system the bit error rate floor caused by time dispersion is reduced by employing a joint minimum mean square error (MMSE) equalizer for all of the respective transmit antenna—receive antenna pairings that are possible in the MIMO system. The resulting joint equalization compensates not only for the impact of the channel on the transmit antenna—receive antenna pairings but also for the interference of the other transmit antennas on any given receive antenna. The joint equalization outperforms simply replicating the prior art minimum mean square error (MMSE) equalizer for each transmit antenna—receive antenna pairings.

Method Of Receiver Processing Of Cdma Signals In A Cdma System

View page
US Patent:
7660340, Feb 9, 2010
Filed:
Jun 22, 2004
Appl. No.:
10/872359
Inventors:
Laurence Mailaender - New York NY, US
Assignee:
Alcatel-Lucent USA Inc. - Murray Hill NJ
International Classification:
H04B 1/00
US Classification:
375147, 375233
Abstract:
The method of receiver processing of CDMA signals in a CDMA system includes first converting a received signal in the time domain to a received signal in the frequency domain, and equalizing the received signal in the frequency domain using a set of frequency domain weights. The equalized received signal in the frequency domain is converted to an equalized received signal in the time domain. The set of frequency domain weights are adaptively adjusted at a symbol rate of the received signal in the time domain based on an error signal produced from the received signal in the frequency domain and a frequency domain representation of a known pilot signal of the CDMA system.
