Time Domain Equalization For Discrete Multi-Tone Systems

View page
US Patent:
6785328, Aug 31, 2004
Filed:
Dec 17, 2002
Appl. No.:
10/320920
Inventors:
Gopal Harikumar - Norwood MA
Daniel J. Marchok - Buchanan MI
Kenneth J. Rudofski - Chicago IL
Assignee:
Tellabs Operations, Inc. - Naperville IL
International Classification:
H04B 110
US Classification:
375232, 375350
Abstract:
A multiple carrier communication system includes a primary impulse shortening filter that receives an output signal of an analog to digital converter and accepts coefficients. A secondary impulse shortening filter receives the output signal of the analog to digital converter, outputs an output signal, and passes coefficients to the primary impulse shortening filter. A reference signal generator outputs a reference signal. A comparator compares the output signal and the reference signal and outputs a resulting error signal. An adaptive processor computes coefficients for the secondary impulse shortening filter based on the error signal.

Boosting A Signal-To-Interference Ratio Of A Mobile Station

View page
US Patent:
7242958, Jul 10, 2007
Filed:
Sep 8, 2005
Appl. No.:
11/222475
Inventors:
Sae-Young Chung - Waltham MA, US
Dae-Young Kim - Lexington MA, US
M. Vedat Eyuboglu - Concord MA, US
Gopal Harikumar - Waltham MA, US
Assignee:
Airvana, Inc. - Chelmsford MA
International Classification:
H04Q 7/20
US Classification:
455522, 455 6711
Abstract:
Techniques for transmitting encoded data packets to one or more mobile stations in a communication system including a cell that has sectors serving at least partially different geographic areas. The techniques include transmitting in a first sector an encoded data packet in one or more time slots to a mobile station; reducing transmission power in a second sector during one or more of the time slots in which the first sector transmits the data packet to the mobile station; decoding at the mobile station the encoded data packet after each time slot; transmitting by the mobile station a signal indicating acknowledgment of the packet reception when the decoding of the packet is successful; and in response to receiving the acknowledgement signal, ceasing transmission of the data packet in the first sector in subsequent time slots.

Spectrally Constrained Impulse Shortening Filter For A Discrete Multi-Tone Receiver

View page
US Patent:
7430242, Sep 30, 2008
Filed:
Jun 7, 2007
Appl. No.:
11/759789
Inventors:
Gopal Harikumar - Waltham MA, US
Daniel J. Marchok - Buchanan MI, US
Assignee:
Tellabs Operations, Inc. - Naperville IL
International Classification:
H04L 27/28
H04B 1/10
US Classification:
375260, 375350
Abstract:
A channel in a multiple carrier communication system is equalized by computing a target spectral response, shortening the impulse response of the channel so that a significant part of an energy of the impulse response is confined to a region that is shorter than a target length and filtering the signal based on the target spectral response.

US Patent:
7603127, Oct 13, 2009
Filed:
Oct 12, 2001
Appl. No.:
09/976240
Inventors:
Sae-Young Chung - Waltham MA, US
Dae-Young Kim - Lexington MA, US
M. Vedat Eyuboglu - Concord MA, US
Gopal Harikumar - Waltham MA, US
Assignee:
Airvana, Inc. - Chelmsford MA
International Classification:
G06F 15/16
US Classification:
455453, 455447
Abstract:
In a cell of a cellular wireless communication system, the SIR of at least one user in a sector of the cell is altered by temporarily reducing transmissions on a forward link in at least one other sector of the cell or a sector in another cell in accordance with a pattern.

US Patent:
7672682, Mar 2, 2010
Filed:
Mar 28, 2006
Appl. No.:
11/392230
Inventors:
Vivek Sharma - Chelmsford MA, US
Sundar Raman - Westford MA, US
Rayadurgam Ravikanth - Acton MA, US
Gopal Harikumar - Westford MA, US
Woojune Kim - Arlington MA, US
Srinivas Kappla - Nashua NH, US
Satish Grandhi - Carlisle MA, US
Assignee:
Airvana, Inc. - Chelmsford MA
International Classification:
H04Q 7/20
H04B 1/16
H04B 1/38
US Classification:
455458, 455574, 4553431
Abstract:
In a radio access network, techniques for determining how often an aces terminal in communication with the network is to monitor a channel of the network based on trigger information received from the access terminal that is specific to one or more of the following: a state of the terminal, a state of a premium application, and a user of the terminal. The trigger information includes information about one or more of the following: a power mode of the access terminal, a user profile identification, an activation of a premium application on the terminal, and a terminal of a premium application on the terminal.

Network-Initiated Session Recovery

View page
US Patent:
7730189, Jun 1, 2010
Filed:
Nov 22, 2006
Appl. No.:
11/562662
Inventors:
Gopal Harikumar - Westford MA, US
Woojune Kim - Arlington MA, US
Dennis Ng - Northboro MA, US
Sanjay Cherian - Brookline MA, US
Assignee:
Airvana, Inc. - Chelmsford MA
International Classification:
G06F 15/16
US Classification:
709227, 370338
Abstract:
Techniques for network-initiated session recovery are described. A relationship is maintained between two identifiers both associated with a session between a first device and an access terminal in a wireless network. The first identifier is associated with the first device, and the second identifier is associated with a second device in communication with the first device. After a breach of the session, communications associated with the session are preserved based on the relationship between the first and second identifiers.

Reverse Link Power Control

US Patent:
7843892, Nov 30, 2010
Filed:
Apr 28, 2004
Appl. No.:
10/835537
Inventors:
Sepehr Mehrabanzad - Southborough MA, US
Satish Ananthaiyer - Tewksbury MA, US
Gopal Harikumar - Westford MA, US
Assignee:
Airvana Network Solutions, Inc. - Chelmsford MA
International Classification:
H04B 7/216
H04B 7/00
US Classification:
370342, 3703102, 455522
Abstract:
This description describes examples of performing reverse link power control in a mobile network having a plurality of first modem devices that receive and transmit signals to wireless access terminals (ATs) and a second device in communication with the plurality of first devices. One of the first devices derives a first power control threshold (PCT) value for reverse link power of one of the access terminals (ATs) and the second device derives a second power control threshold (PCT) value for reverse link power of the one of the ATs. The second power control threshold (PCT) value is transmitted using a data traffic path and either the first PCT value or the second PCT value is selected.
