| Abstract: | The main components of the serially concatenated trellis coded modulation (SCTCM) are serially concatenated convolutional code (SCCC) and trellis coded modulation (TCM). Based on these two techniques, the structure and the design rules of SCTCM are proposed in this paper. According to the complicated time varying property of the satellite mobile communication channel, the BER performance of SCTCM in this kind of channel is analyzed and an upper bound is given. At last the computer simulation is implemented with reference to 64 state TCM. The simulation results show that SCTCM is valuable in satellite mobile communications. |
