Abstract

Limited bandwidth, unwanted signal interference in the atmosphere medium during transmission and low data rate transfer among others are the challenges bedeviling communication systems. Hence, the introduction of Trellis Coded Modulation (TCM) system to address these fundamental causes of inefficient and unreliable communication from the transmission point to the consumers has become paramount. The choice of this system, an efficient coding technique improves the coding gain at no extra cost in bandwidth with respect to expansion. Ensures reliable high data rate communication over channels with limited bandwidth at far higher speeds from previously envisaged. The performance of trellis codes on M-ary phase shift keying (MPSK) and M-ary Quadrature Amplitude Modulation (MQAM) shows tremendous coding gain.
