Abstract： |
A united decode equalizer in block shape includes block interlacer and multiplexer at transrnitting end of communication system, the feedforward filter at receiving end, demultiplexer and deinterlacer, noise predicting and counterbalancing module and the module of coefficient predicting and interpolation. The output of TCM code at transmitting end will be interlaced by interlacer and to be multiplexed with training series; the receiving signal will pass the multiplexer first and the exported training series part to be sent to module of coefficient training and interpolation for obtaining the module coefficient for feedforward filter, noise predicting and counterbalancing and the output of noise predicting and counterbalancing module to be sent to TCM decoder for decoding; the judging result will be fedback to noise predicting module. The present invention has realized the combination of equalizing and decoding tor raise the performance of intersymbol interferences as well as provided a new method of resisting channel time varying and intersymbol interference in single carrierwave wide band of radio communication. |
