Linear Minimum Mean Square Error Equalization With Interference Cancellation For Mobile Communication Forward Links Utilizing Orthogonal Codes Covered By Long Pseudorandom Spreading Codes
view source
US Patent:

6956893, Oct 18, 2005
Filed:

Aug 20, 2001
Appl. No.:

09/933365
Inventors:

Colin D. Frank - Lombard IL, US
Eugene Visotsky - Skokie IL, US
Prashant Choudhary - Schaumburg IL, US
Amitava Ghosh - Buffalo Grove IL, US
Assignee:

Motorola, Inc. - Schaumburg IL
International Classification:

H04K001/00
US Classification:

375147, 375232, 375346
Abstract:

The present invention provides linear MMSE equalization with parallel interference cancellation for symbol determination in a forward link of a CDMA communication system which has a plurality of code channels in use. Use of the linear MMSE equalization with parallel interference cancellation of the present invention provides significantly increased performance. The preferred method linearly filters a received signal to form a first filtered signal (), despreads and demodulates the first filtered signal () and provides a plurality of symbol estimates for all corresponding code channels (). An estimated transmitted signal is generated from the plurality of symbol estimates (), and with a channel estimate (), an estimated received signal is generated (). A residual signal is determined as a difference between the received signal and the estimated received signal, is linearly filtered (), and then combined with the estimated transmitted signal to form a next, enhanced estimated transmitted signal (). This next estimated transmitted signal is despread () and utilized to provide a next plurality of symbol estimates, for a selected code channel of the plurality of channels, for subsequent use in error correction and decoding, and further use by a subscriber ().

US Patent:

7400856, Jul 15, 2008
Filed:

Sep 3, 2003
Appl. No.:

10/654227
Inventors:

Philippe J. Sartori - Algonquin IL, US
Kevin L. Baum - Rolling Meadows IL, US
Brian K. Classon - Palatine IL, US
Mark Cudak - McHenry IL, US
Vijay Nangia - Schaumburg IL, US
Eugene Visotsky - Skokie IL, US
Assignee:

Motorola, Inc. - Schaumburg IL
International Classification:

H04B 3/36
US Classification:

455 7, 455 9, 455 10, 455 111, 370315
Abstract:

Communications sourced by a remote unit () that is already within reception range of a base site () can nevertheless be further facilitated through allocation of one or more relay resources (). Such relay resources, properly employed, then serve to effectively increase the quality of service for the facilitated communication. This, in turn, can permit the use of, for example, increased data rates for communications from a relatively low power remote unit.

US Classification:

455447, 455448, 455 411, 455 412, 455 413, 455454
Abstract:

A technique for dynamic spectrum sharing includes identifying () a plurality of radio nodes (), measuring () a local signal value (SV) at each radio node (), and determining () a transmit decision. Each radio node can measure a local signal value (SV) of a protected transmission and the radio nodes are within a uniform SV region of the protected transmission. The transmit decision is determined for at least one of the plurality of radio nodes based on the SV of each radio node in the plurality of radio nodes and at least one threshold value that is related to statistical characteristics of the protected transmission at an interference boundary () of the protected transmission and a desired probability of non-interference with the protected transmission at the interference boundary.

Abstract:

A DTV signal detector detects DTV signals received by a receiver on a selected DTV channel in a Digital Television System. The DTV detector includes a first DTV signal detector that detects a first characteristic of the received DTV signals, and a second DTV signal detector that detects at least a second characteristic of the received DTV signals. A controller responds to the first DTV signal detector and the second DTV signal detector to control a selection of the DTV channel being selected by the receiver. The receiver can be synthesized to select from more than one DTV channel.
