Multiple Input Multiple Output (MIMO) technology significantly enhances signal transmission rates and system reliability through multi-antenna systems. To improve spectral efficiency and anti-interference capabilities, spatial modulation technology, as an extension of MIMO, has been proposed and widely applied. Generalized Spatial Modulation (GSM) further integrates multiple modulation schemes, enhancing the system's performance. Polar codes, as an efficient error correction code, leverage channel polarization to transform physical channels into virtual channels with varying levels of reliability, thus effectively improving the performance of MIMO and spatial modulation systems. This paper presents a decoding scheme for multi-user polar codes, aimed at optimizing the decoding process in the uplink Polar Coded-Generalized Spatial Modulation (PC-GSM) system. By combining the channel polarization characteristics of polar codes with the advantages of GSM, the scheme improves decoding algorithms, enhancing the reliability and data transmission rate of multi-user systems. Simulation results show that the proposed decoding scheme significantly boosts system performance, providing a novel solution for the integration of multi-user polar codes and spatial modulation technology.

多输入多输出(Multiple Input Multiple Output,MIMO)技术通过多天线系统显著提升信号传输速率和系统可靠性。为提高频谱效率和抗干扰能力,空间调制技术作为MIMO的扩展被提出并得到广泛应用。广义空间调制(Generalized Spatial Modulation,GSM)进一步结合多种调制方式,提升系统性能。极化码作为高效的纠错码,通过信道极化将物理信道转化为具有不同可靠性的虚拟信道,有效提高MIMO和空间调制系统的性能。提出一种联合多用户的极化码译码方案,旨在优化在上行极化码广义空间调制(Polar Coded-GSM,PC-GSM)系统中的译码过程。该方案结合了极化码的信道极化特性和GSM的优势,通过改进译码算法,提升了多用户系统的可靠性和数据传输速率。仿真结果表明,所提出的联合译码方案能够显著提高系统性能,为极化码与多用户空间调制系统的结合提供新的解决思路。
