摘要

空时移位键控（space-time shift keying，STSK）是一种用于多输入多输出（multi-input multi-output， MIMO）通信系统的调制方案，通过预先设计的色散矩阵集（dispersion matrix set，DMS）以实现系统在复用与分集之间的灵活设计。提出了改进的遗传算法（genetic algorithm，GA）辅助DMS和3D星座的联合优化，即将DMS和3D星座联合编码作为GA的染色体，并采用秩与行列式准则对应的编码增益作为总体适应度值。通过高效的选择以及改进的变异和交叉策略，可以获得低误码率（bit error rate，BER）的DMS和3D星座，同时利用3D星座的对称性，大幅度降低了编码增益对应的适应度值的计算复杂度。推导了3D STSK方案的理论平均成对差错概率（ABEP）。仿真结果表明，与传统的 GA 和随机搜索方案相比，本文提出的改进 GA在保证BER性能前提下可以显著降低系统实现的复杂度。

Abstract

Space-time shift keying (STSK) is a modulation scheme used in multi-input multi-output (MIMO) communication systems.It uses a pre-designed dispersion matrix set (DMS) to realize the flexible design of the system between multiplexing and diversity.An improved genetic algorithm (GA) was proposed to assist the joint optimization of DMS and 3D constellations

that is

the DMS and 3D constellations were jointly coded as the chromosome of GA

and the coding gain corresponding to the rank and determinant criterion was adopted as the overall fitness value.Through efficient selection and improved mutation and crossover strategies

DMS and 3D constellations with low bit error rate (BER) can be obtained.At the same time

the symmetry of the 3D constellation was used to greatly reduce the computational complexity of according to the fitness value the coding gain.The theoretical average paired error probability (ABEP) of the 3D STSK scheme was deducted.The simulation results show that

compared with the traditional GA and random search schemes

the improved GA proposed can significantly reduce the complexity of system implementation while ensuring BER performance.
