US Patent:

58191682, Oct 6, 1998

Filed:

May 1, 1997

Appl. No.:

8/850027

Inventors:

Glenn David Golden - Boulder CO
Carol Catalano Martin - Fair Haven NJ
Nelson Ray Sollenberger - Tinton Falls NJ
Jack Harriman Winters - Middletown NJ

Assignee:

AT&T Corp - Middletown NJ

International Classification:

I04B 110

US Classification:

455303

Abstract:

A communication system and method, particularly adapted for use in adaptive antenna arrays, are presented. A plurality of signals containing a desired signal, interference, and noise are received through an array of antennas connected to a base receiving station. The signal arriving at each antenna is weighted according to computations which adjust those weights as a function of received interference and noise power in an unequal manner, based on the estimation accuracy of the interference and noise, which in turn depends on factors such as interference to noise power ratios and fading rate.

Assignee:

AT&T Corp - New York NY

International Classification:

H04L 102
H03G 1104

US Classification:

375347

Abstract:

A system and method for applying channel weights in a communication system are presented. The application of weights derived from a sample window is time-shifted into that sample window, decreasing the effects of channel variation and partially compensating for degradation due to differential detection.

US Classification:

375347

Abstract:

A system and method for generating a coherent reference signal for extracting desired user signals from received signals even after error propagation is underway, are presented. A data symbol preceding a sequence whose relative phases are known is used as an absolute phase reference. Since errors in detection of the phase reference symbol are usually caused by error propagation already underway, the sequence can be used to reacquire the desired signal with merely an absolute phase shift in detected data, which allows accurate differential detection of the desired user signal even in the absence of absolute phase knowledge.
