Abstract :
A multifrequency channel transmission method for trellis-coded quadrature amplitude modulation (QAM) that uses an interleaving function to improve bit error rate (BER) performance under Rayleigh fading environment conditions is described. A multifrequency channel transmission method for trellis-coded modulation (TCM) that uses interleaving is proposed to distribute the burst error that occurs in the time and frequency domains, and its performance is examined by computer simulation. Computer simulation shows that this method should be useful for land mobile communications
