| dc.description.abstract | The increasing demand of the frequency spectrum for land mobile satellite communication services has led to the approach of moving the current operating frequency up to EHF (30/20 GHz) band. In this thesis, the propagation characteristics of the EHF mobile satellite communication channel are estimated and modeled. Conventional and multiple trellis-coded modulation schemes designed for fading environment are considered for the EHF mobile satellite channel. The design criteria for optimum trellis-coded modulation scheme on the folding channel are studied. Through computer simulation, the performances of both coherent and differential trellis-coded modulation systems with selected coding schemes on the EHF channel models are evaluated. The effects of using channel state information and interleaving technique on the trellis-coded modulation systems are also studied. Finally the simulation results are presented and discussed. | |
