Abstract :
The Canadian mobile satellite (MSAT) channel has been modelled as the sum of lognormal and Rayleigh components to represent foliage attenuation and multipath fading, respectively. Several authors have applied trellis coded modulation (TCM) schemes to this channel, estimating the bit error performance via computer simulation. In this paper, a general expression is presented for the pair-wise error probability (PEP) of TCM schemes transmitted over this channel under ideal interleaving. The expression can be specialized to several cases including ideal coherent detection, pilot-tone aided detection, and differential detection. The results are substantiated by means of computer simulation
