摘要
分析了影响级连STCM(Space TimeCodedModulation)性能的几个因素 ,研究了级连STCM在不同信道环境下的性能 ,指出基于传统最小化误帧率原则优化的STCM编码方式并不适合级连 .通过 3GPP环境下的仿真与级连STTD(Space TimeTransmitDiversity)进行了比较 。
Several factors that influence Concatenated Space Time Coded Modulation are analyzed. The performance of Concatenated STCM in various channels is studied. The result shows that the optimized STCM based on minimized FER is not suitable for concatenation. Performance comparison with concatenated STTD by simulation in 3GPP indicates that Concatenated STCM would perform better.
