Channel precoder using an infinite impulse response filter

摘要

A trellis coded modulation (TCM) transmitter-receiver (transceiver) including a TCM transmitter for transmitting, and a TCM receiver for receiving and decoding a transmitted signal, wherein said transmitter includes a TCM encoder, a precoder, a transmitter and a TCM receiver. The precoder receives the output of the TCM encoder and removes expected intersymbol interference from the output of the TCM encoder. The precoder includes an Infinite Impulse Response (IIR) filter. The transmitter transmits the output of the precoder. The TCM receiver receives and decodes a transmitted signal. <IMAGE>
