Shared Resources Modulator-Demodulator Circuits For Use With Quadrature Amplitude Modulated Signals

US Patent:
5692013, Nov 25, 1997
Filed:
Nov 7, 1995
Appl. No.:
8/554696
Inventors:
Joshua Lawrence Koslov - Hopewell NJ
Frank Anton Lane - Medford Lakes NJ
Carl G. Scarpa - Somerset NJ
Assignee:
Hitachi America, Ltd. - Tarrytown NY
International Classification:
H04L 2710
US Classification:
375277
Abstract:
A common transceiver circuit for use as either a modulator or demodulator and that is implemented through a shared resource approach. This approach is particularly, though not exclusively, suited for with quadrature amplitude modulated (QAM) or vestigial sideband (VSB) signals. Specifically, a QAM transceiver circuit (400), through strategically located multiplexing stages, physically re-uses both a complex Nyquist filter (310, 320) and an equalizer (140) for demodulation and modulation. Additionally, tap coefficients of the complex Nyquist filter are set such that a center frequency of an otherwise baseband Nyquist filter is translated upward to a symbol rate in order to eliminate a separate complex mixer (250, 260). Similarly, a VSB transceiver circuit (700), also through strategically located multiplexing stages, physically re-uses a complex vestigial Nyquist filter (610), a complex mixer (620) and an equalizer (785) during demodulation and modulation. The VSB transceiver also selects a particular configuration of a common complex Hilbert transform circuit (720) for use during either demodulation or modulation.

Apparatus And Methods For Tile And Assignment Processing

US Patent:
8149936, Apr 3, 2012
Filed:
Mar 27, 2009
Appl. No.:
12/412362
Inventors:
Joshua Lawrence Koslov - Hopewell NJ, US
Irv Negrin - Ringwood NJ, US
Jingyuan Liu - Morris Plains NJ, US
Niranjan N. Ratnakar - Hillsborough NJ, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04K 1/10
US Classification:
375260, 370209
Abstract:
Disclosed are methods and apparatus for synchronizing tile processing and assignment processing in a communication device. In particular, the methods and apparatus utilize a tile processing scorecard with a number of assertable bits corresponding to a number of tiles to be tile processed. As each tile is tile processed, the scorecard or bit indicators are asserted to indicate that the tile has been processed. Assignment jobs, which involve codewords having information from symbols in multiple tiles are processed after all of the pertinent tiles are tile processed. The scorecard information is accessible for assignment processing to determine which tiles have been processed, thus affording synchronization of tile processing with assignment processing, while maximizing the independence of these two processing operations. Tile processing operations may further use the scorecard information to prioritize or order tile processing in relation to known queued assignment jobs.

Service In Communication Systems

US Patent:
2010006, Mar 18, 2010
Filed:
Dec 14, 2006
Appl. No.:
12/448224
Inventors:
Joshua Lawrence Koslov - Hopewell NJ, US
Wen Gao - West Windsor NJ, US
Yik Chung Wu - West Windsor NJ, US
International Classification:
H04B 17/00, H04L 27/06
US Classification:
375227, 375340
Abstract:
A method and apparatus for improving performance in communication systems is provided. In one implementation, initial encoded data that has been encoded with a rateless code is received. A quality metric is determined for a communication medium on which the initial encoded data has been received. A modulation scheme used in sending the initial encoded data on the communication medium is identified. An estimate is determined, based on the identified modulation scheme and the determined quality metric, of an amount of mutual information being received per unit of received encoded data. An amount of mutual information being received is determined, based on the determined estimate.

Methods And Apparatus For Implementing Multi-Tone Receivers

US Patent:
7127019, Oct 24, 2006
Filed:
Jun 21, 2001
Appl. No.:
09/886591
Inventors:
Joshua L. Koslov - Hopewell NJ, US
Assignee:
Hitachi, Ltd. - Tokyo
International Classification:
H04L 7/00, H03D 1/04
US Classification:
375371, 375346
Abstract:
Methods and apparatus for reducing phase jitter in a multi-tone, e. g. , OFDM, receiver are described. A jitter compensation filter is used to process a received signal following timing recovery and/or channel compensation to reduce and/or eliminate the effect of phase jitter. Jitter compensation filter tap weights are updated after filtering the received signal based on one or more signal error measurements. The same received signal is filtered using the updated filter, and error measurements generated from the filtered signal are used to once again update the filter's tap weights. After a fixed number of filter update cycles and/or some other filter updating stop criterion being satisfied, the filter updating process is stopped and the filtered signal is used, e. g. , supplied to additional receiver circuitry.

Method And Apparatus For Carrier Recovery Using Multiple Sources

US Patent:
2008021, Sep 11, 2008
Filed:
Nov 16, 2004
Appl. No.:
11/667783
Inventors:
Joshua Lawrence Koslov - Hopewell NJ, US
Assignee:
THOMSON LICENSING - Boulogne-Billancourt
International Classification:
H04L 27/22
US Classification:
375326
Abstract:
In a receiver, a decision-directed phase estimator is used in conjunction with an interpolator to provide a phase estimate for use in carrier recovery. For example, a receiver comprises a pilot phase estimator, a Costas loop and an interpolation controller. The pilot phase estimator provides determined phase estimates at the pilot times and the interpolation controller provides interpolated phase estimates at other times as a function of a linear interpolation based on a respective determined phase estimate and at least one decision-directed phase error estimate from the Costas loop.

Reduction Of Overhead In A Multiple-Input Multiple-Output (Mimo) System

US Patent:
2010006, Mar 18, 2010
Filed:
Dec 6, 2006
Appl. No.:
12/312765
Inventors:
Joshua Lawrence Koslov - Hopewell NJ, US
Wen Gao - West Windsor NJ, US
Yik-Chung Wu - Sheung Shui, HK
International Classification:
H04L 1/02, H04W 72/00
US Classification:
375267, 370329
Abstract:
A multi-access multiple-input multiple-output (MIMO) system comprises a base station (BS) and a number of user equipment (UE), N, for serving N users. The BS divides the N users into L mobility groups, where each mobility group is associated with a certain range of channel dynamics. Those mobility groups having lower channel dynamics—that is, the channel dynamics change less rapidly—are updated with beamforming information less frequently than those mobility groups having higher dynamics—that is, the channel dynamics change more rapidly.

The transmitter transmits the sequential portions of data separated by respective time intervals having lengths configured to allow a receiver to enter and exit a power saving mode between receiving sequentially transmitted portions of data from the first set of data (). The transmitter separates sequential portions of data in a second set by time intervals that are not of sufficient length to allow a receiver to enter and exit a power saving mode during the time intervals (). The second set of data is then transmitted ().

Adaptive Soft Demodulation For Reception Of Distorted Signals

US Patent:
7464318, Dec 9, 2008
Filed:
Apr 24, 2004
Appl. No.:
10/554580
Inventors:
Joshua Lawrence Koslov - Hopewell NJ, US
Kumar Ramaswamy - Princeton NJ, US
Wen Gao - Plainsboro NJ, US
Assignee:
Thomson Licensing - Boulogne Billancourt
International Classification:
H03M 13/00
US Classification:
714759, 714780
Abstract:
A satellite communications system comprises a transmitting ground station, including a transmitter and a receiver, a satellite transponder and a receiving ground station. The transmitter transmits an uplink signal to the satellite transponder, which broadcasts the received uplink signal as a downlink signal to the receiving ground station. The transmitting ground station monitors the downlink signal through the receiver and calculates log-likelihood ratios (LLRs) as a function of the monitored downlink signal. These LLRs are illustratively stored in a look-up table, which are then transmitted to the receiving ground station for use in recovering data from a received data signal.
