Abstract

Multiple trellis coded modulation (MTCM) which assigns more than one signal per trellis branch achieves better signal diversity than conventional TCM for the transmission of digital information on a fading channel. The paper above presents a set partitioning method which was claimed to maximize the effective length (L_min) and the minimum product distance (d_pmin). In this paper, it is observed that this set partitioning did not take into account that the MPSK signal sets (M> 4) are nonregular where then the worst case distance corresponding to each signal selector should be considered
