摘　　要：基于空间调制系统采用APM数字调制星座的传输性能分析,提出了一种适用于空间调制传输系统的APM数字调制星座产生方法。该方法可获得具有多圈结构的PSK数字调制星座,即每圈的星座点符合等相位间隔分布的传统PSK调制星座。而且通过详细分析星座点分布对传输性能的影响,结合方便设计的考虑,提出了数个设计准则;在设计准则的指导下提出了多圈PSK数字调制星座的设计过程,依据该过程可以有效获得性能优良的多圈PSK数字调制星座。实验结果也进一步证实,新设计的多圈PSK数字调制具有优于传统PSK和QAM数字调制的性能。Based on the transmission performance analysis of spatial modulation(SM)with APM digital modulation constellation,a novel APM digital modulation constellation design method suitable for SM transmission is proposed.This method can obtain a PSK digital modulation constellation with a multi-ring structure,that is,the constellation points of each ring conform to the traditional PSK modulation constellation with equal phase interval distribution.Furthermore,by analyzing the influence of constellation point distribution on transmission performance in detail,combined with the consideration of convenient design,several design criteria are proposed.Under the guidance of these design criteria,the design process of multi-ring PSK digital modulation constellation with good performance is proposed.The experimental results further confirm that the newly designed multi-ring PSK digital modulation perform better than the traditional PSK and QAM digital modulation.
