International Classification:

G06F 11/00

US Classification:

714 15, 714 47

Abstract:

The invention provides methods and apparatus for multiple user detection (MUD) processing that have application, for example, in improving the capacity CDMA and other wireless base stations. One aspect of the invention provides a multiprocessor, multiuser detection system for detecting user transmitted symbols in CDMA short-code spectrum waveforms. A first processing element generates a matrix (hereinafter, “gamma matrix”) that represents a correlation between a short-code associated with one user and those associated with one or more other users. A set of second processing elements generates, e. g. , from the gamma matrix, a matrix (hereinafter, “R-matrix”) that represents cross-correlations among user waveforms based on their amplitudes and time lags. A third procesing element produces estimates of the user transmitted symbols as a function of the R-matrix.

US Classification:

Abstract:

A semi-automatic power control in component architecture system is provided. Using a component based hardware (HW) and software (SW) architecture, semi-automatic power control in component architecture systems is achieved. Further, intelligent power control in heterogeneous architectures is achieved by the knowledge of the data communications between components, both hardware and software. The analysis of the data traffic, embedded-in the traffic clues, and/or special messages, enable a decentralized highly efficient semi-automatic power control scheme to be employed on SOC, and extended to the rest of the digital processing systems within one device or system.
