摘要
Abstract
Based on the principle of MHPSK and TCM,the MHPSK-TCM scheme is proposed. In this paper, we inves-tigate the set partitioning of 16HPSK and construct a 16HPSK-TCM encoding modulator in detail. Moreover,a soft decision Viterbi decoding algorithm based on symbols of MHPSK-TCM is given. Simulation results show that communication systems which employ MHPSK-TCM(M≥8) can acquire 2dB gain,as BER is 1e-5. In addition,MHPSK-TCM scheme also has many virtues such as equal energy symbols and high spectral efficiency. Therefore,the proposed scheme can offer a good ap-plication in the energy-constrained wideband satellite systems.关键词
