Abstract (2. Language): 
In this paper, the performance of Space-Time - Turbo Trellis Coded Modulation (ST-TTCM) is evaluated over Rician fading channels with imperfect phase reference. For high data transmission over wireless fading channels, Space-Time Block Codes provide the maximal possible diversity advantage for multiple decoding algorithms. The combined effects of fading channel and non-ideal coherent receiver on the phase of the received amplitude and of a noisy carrier reference are considered, each modeled by Rician and Tikhonov distributions respectively. Here, we investigate Space Time-Turbo Trellis Coded Modulation (ST-TTCM) for 8PSK for several Rician parameters K and effective signal-to-noise ratio in the carrier tracking loop a. Thus, our results will reflect the degradations both due to the effects of the fading on the amplitude of the received signal and of a noisy carrier reference.
