Abstract: In order to approach higher requirements of coding and modulation for the sixth generation of mobile communications system,a faster than Nyquist(FTN)transmission scheme based on constellation shaping is proposed. Probabilistic shaping and geometric shaping in FTN transmission is investigated,and the average mutual information is analyzed theoretically. The simulations show that the proposed quadrature amplitude modulation(QAM) FTN transmission scheme based on probabilistic shaping has better average mutual information and error rate performance.

Key words: constellation shaping, faster than Nyquist, average mutual information, the sixth generation of mobile communications system
