    摘要: Determination of equalizer coefficients from a sparse channel estimate begins by determining location of significant taps based on the sparse channel estimate of a multiple path communication channel. The sparse channel estimate indicates the positioning of signals received via the various multiple paths of the channel. The method then continues by determining feed-forward equalization coefficients based on the location of the significant taps. The method then continues by determining feedback equalization coefficients based on the feed-forward equalization coefficients and the sparse channel estimate.

    摘要: An adaptive receiver is disclosed for optimally receiving and processing signals. The receiver utilizes one or more memory blocks to store groups of incoming symbols. The groups of symbols are processed by a channel estimation subsystem to determine channel characteristics. The receiver determines the appropriate demodulation and decoding strategy to implement based on the determined channel characteristics. The receiver includes a plurality of demodulation and decoding schemes, one of which is selected based on the results of a channel estimation analysis.

    摘要: Sparse channel equalization may be achieved by receiving a signal via a multi-path communication channel. The equalization then continues by extracting sparse information regarding the multiple path communication channel from the signal. Such sparse information generally indicates the position of the signals received via each of the multiple paths. The equalization then continues by estimating a channel response of the multiple path communication channel based on the sparse information. The equalization then continues by generating equalization taps (or coefficients) based on the channel response. The equalization then continues by equalizing the signal based on the equalization taps.
