Abstract :
An adaptive scheme for trellis coded modulation of multiple phase shift keying (MPSK) signals, called adaptive trellis coded MPSK (ATCMPSK), is proposed for the Rayleigh fading channel. The adaptive scheme is based on varying the coding/modulation (codulation) rate according to channel conditions. Slow fading and ideal channel information at the receiver are assumed. It is shown that ATCMPSK results in a considerable improvement in bit error rate (BER) performance of MPSK signals under fading
