摘　　要：为了提高空间调制系统的可靠性,本文提出了一种基于卷积编码辅助设计发射天线星座图的空间调制系统,有效利用卷积码的纠错能力,提高MIMO通信系统的误码性能.仿真实验结果表明:在同一条件下,基于卷积编码辅助设计发射天线星座图的空间调制系统优于汉明码辅助设计星座图的空移键控调制系统和网格编码空间调制系统,分别有10 d B和8 d B的增益.In order to improve the reliability of the space modulation system, this paper proposes a type of spatial modulating system based on convolution code-aided transmitting antenna constellation spatial modulation system. The proposed scheme employs the error-correcting ability of the convolution code to improve the performance of the MIMO communication system. Simulation results show that under the same conditions, the spatial modulation system based on the transmitting antenna constellation diagram aided by convolutional coding is superior to the shift keying modulation system based on the constellation graph aided by the Hamming code and to the spatial modulation system based on the trellis code, respectively with an extra gain of 10 d B and 8 d B.
