Daa Concept With Uplink Detection: Frequency Domain Quiet Periods

View page
US Patent:
20080268779, Oct 30, 2008
Filed:
Mar 31, 2008
Appl. No.:
12/080257
Inventors:
Sandeep Rajpal - Irvine CA, US
Siddharth Shetty - San Diego CA, US
Gaetano Roberto Aiello - San Diego CA, US
Timothy Leo Gallagher - Encinitas CA, US
Nishant Kumar - San Diego CA, US
Nicholas Michael Carbone - San Diego CA, US
James Laurence Taylor - Sherborne, GB
International Classification:
H04B 7/00
H04Q 7/00
US Classification:
455 412, 34053911
Abstract:
A victim wireless device is detected by obtaining a set of wireless bands and a set of time periods. During a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data. During each of the time periods in the set of time periods: a signal, if any, is received; in the event a signal is received, the subset of vacant wireless bands corresponding to that time period is recorded; and after the set of time periods ends, it is determined whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.

4 X 4 Dimensional Block Modulation Code For A Pam-5 Constellation

View page
US Patent:
60673265, May 23, 2000
Filed:
Sep 8, 1997
Appl. No.:
8/925552
Inventors:
Olafur O. Jonsson - Reykjavik, IS
Sverrir Olafsson - Seltjarnarnes, IS
Sandeep Rajpal - Irvine CA
Ramin A. Nobakht - Laguna Niguel CA
Assignee:
Conexant Systems, Inc. - Newport Beach CA
International Classification:
H04L 2534
H04L 2549
US Classification:
375286
Abstract:
A method is disclosed for encoding and modulating bits of an information stream and transmitting them over a designated channel in a high speed communication system. The method includes the steps of dividing a set of the entire constellation of available points into a finite plurality of zero parity vectors defined by two criteria, namely that (1) the column vectors have odd parity and (2) a group of a predefined integer number of column vectors have a 0 modulus (i. e. be divisible by a given number). Column vectors forming only a partially dimensioned portion of the code (e. g. 4D) corresponding to one discrete baud interval are preferably transmitted in a systematic form and with sufficient coding gain for adaptive DFE equalization and whereby a group of column vectors corresponding to an integer number of successive baud intervals that form the fully dimensioned code (e. g. 16D) are transmitted with correlation to one another to achieve an even greater amount of coding gain suitable for high reliability data transmission with error correction and subsequent detection that yield a low bit error rate.

Non-Coherent Frequency Shift Keying Detection Scheme

View page
US Patent:
62721844, Aug 7, 2001
Filed:
Dec 17, 1997
Appl. No.:
8/992034
Inventors:
Jonathan H. Ta - Irvine CA
Samuel T. Wong - Rowland Heights CA
Stanley C. Hsieh - Diamond Bar CA
Sandeep Rajpal - Irvine CA
Assignee:
Conexant Systems, Inc. - Newport Beach CA
International Classification:
H03D 300
H04L 2714
US Classification:
375334
Abstract:
A non-coherent frequency shift keying detection scheme. The invention has been applied to the special case of capturing caller ID information when the voice-band modem is in the low power mode. The technique provides the capability for capturing and decoding enough of the caller ID information transmitted by the telephone company while the computer is in the sleep or low power mode, and upon awakening the computer can use this captured information to decode the actual caller ID information. Additionally, this invention automatically accommodates both the Bell 202 or V. 23 transmission standards by utilizing a threshold concept in which the time that has elapsed between the zero crossings of an FSK tone half cycle are measured. The elapsed times may be used as an indication of which FSK tone has been transmitted thus allowing capture of caller ID information. The bit output of the caller ID capture circuit is output for storage by RAM thus allowing use by the computer when it wakes up.

Control Channel For Modems

View page
US Patent:
59109599, Jun 8, 1999
Filed:
Jan 6, 1997
Appl. No.:
8/779084
Inventors:
Sverrir Olafsson - Seltjarnarnes, IS
Sandeep Rajpal - Irvine CA
Assignee:
Conexant Systems, Inc. - Newport Beach CA
International Classification:
H03M 1300
US Classification:
371 371
Abstract:
A methodology for a modem control channel is disclosed. The channel allows faster seamless rate change and precoder tap exchange than the baseline procedure for seamless rate change, allowing for more robust transmission of control information. It can also be use to convey side-information in the case of multiple data applications, serving the purpose of mode switching. Thus, with a single control channel both the needs for seamless rate change and transmitting control information for multiple data applications can be met.
