摘要
针对常规差分空间调制（DSM
differential spatial modulation）方法没有发射分集功能以及接收译码复杂度高的问题，提出一种基于正交空时分组码的差分空间调制（OSTBC-DSM
differential spatial modulation scheme based on orthogonal space-time block code）方案。设计了2个矩阵：空间调制矩阵和符号矩阵，前者通过设置其中非零元素的位置来激活不同的发射天线，后者采用正交空时分组码（OSTBC）作为基本码块来构造符号矩阵。所提方案具有可获得满发射分集、频谱效率高等优点，同时支持线性最大似然（ML
maximum likelihood）译码。仿真结果表明，所提方案在不同的频谱效率下均获得了比其他几种方案更好的误比特率（BER
bit error rate）性能。
Abstract
Focusing on the problem that differential spatial modulation (DSM) couldn’t obtain transmit diversity and has high decoding complexity
a new differential spatial modulation scheme based on the orthogonal space-time block code was proposed and the proposed scheme is called OSTBC-DSM.There were two matrices in this scheme:the spatial modulation matrix and the symbol matrix.The former was aimed to activate different transmit antennas by setting the position of nonzero elements
and the latter structured symbolic matrix by using orthogonal space-time block codes (OSTBC) as the basic code block.The proposed scheme could obtain full transmit diversity and higher spectral efficiency compared with the conventional DSM schemes.Moreover
the OSTBC-DSM supported linear maximum likelihood (ML) decoding.The simulation results show that under different spectral efficiencies
the proposed OSTBC-DSM scheme has better bit error rate (BER) performance than other schemes.
