Abstract: In a hybrid matrix amplifier array (100), a configurable digital transform matrix (116) is initialized with a matrix of transform coefficients. A plurality of digital input signals (M1-M4) are received at inputs of the configurable digital transform matrix (116). The plurality of digital input signals are transformed to produce a plurality of transform digital signals (A1-A4) using the matrix of transform coefficients. The plurality of transform digital signals are converted to a plurality of transformed analoged signals (206) to produce a plurality of transformed analog signals. The transformed analog signals are amplified (104, 208) to produce amplified transformed signals. Finally, the amplified transformed signals are inverse transformed (102, 210) to produce output signals that correspond to a respective digital input signal (M1-M4). Upon sensing a failure in an amplifier array (104, 126) a controller (128) recalls matrix transform coefficients from a memory (130) and write and reconfigures the digital transform matrix (116) to minimize the effects of the amplifier failure at the hybrid matrix amplifier outputs (132).

Abstract: A method and apparatus for routing signals through a system (10) which has multiple destination nodes (12, 14) assigns one or more unique carrier frequencies to each destination node (12, 14). When a signal is received (502) by a transceiver (12), the transceiver (12) evaluates (504) the carrier frequency of the signal, and determines (506) to which destination node (12, 14) that carrier frequency is assigned. The determination (506) is made using a table (200) which associates carrier frequencies to destination nodes (12, 14). The table (200) is created (304) and uptdated by a control facility (20) which distributes (306) the table (200) to the transceivers (12). Once the transceiver (12) determines (506) the destination node (12, 14), the transceiver (12) can route the signal toward that destination node (12, 14).

Abstract: A communication system (100) employs a method and apparatus for mitigating distortion effects and enhancing signal usability determinations in a receiver (102). The receiver receives a discrete information signal that includes a stream of information symbols. Each information symbol (124) of the stream includes two components: a desired component and an undesired component that includes interference and distortion. The receiver determines an estimate (126) of the desired component of an information symbol and an estimates (130) of the undesired component of the information symbol based on the information symbol itself and its desired component estimate. The undesired component estimate is then scaled by a scaling factor (132) that is derived based on the desired component estimate. An enhanced determination of signal usability (136) for the received symbol is finally determined based on the scaled undesired component estimate (134). In this manner, the enhanced signal usability determination approaches being a function of interference only, substantially exclusive of distortion.
