Performance of Turbo TCM/FPM scheme in a DS/SSMA system over multipath Rician fading channel

The synergy between frequency arid phase modulation (FPM) using trellis-coded modulation (TCM) leads to greater gains than can be achieved using conventional TCM/MPSK modulation. An iterative structure is introduced into a TCM/FPM scheme to give a new scheme, the Turbo TCM/FPM scheme. Simulation results show that the new scheme can achieve a significant performance improvement with respect to the Turbo TCM 8PSK and TCM/FPM schemes, respectively, in a DS/SSMA system over a multipath Rician fading channel.
