On the performance of trellis coded M-PSK systems over Rician fading channels with phase jitter 

Uysal, Murat; Aygölü, Ümit; Panayırcı, Erdal (Assoc Elettrotecnica Ed Elettronica Italiana, 2001-02)
In this paper, the performance of trellis coded M-PSK systems is investigated operating over Rician fading channels with phase jitter. Thus the results reflect not only the degradation due to the effect of fading on the ...
