摘要 本文把空时编码(STC)技术应用于正交多载波直接序列扩频CDMA(MC-DS-CDMA)系统,给出了空时编码MC-DS-CDMA系统的发射机和接收机方案。计算机仿真给出了应用空时编码的MC-DS-CDMA系统性能,和普通MC-DS-CDMA以及应用空时编码的多载波CDMA(MC-CDMA)系统的性能比较也由计算机仿真给出。 Space-time codes are applied to orthogonal multicarrier direct sequence CDMA (MC-DS-CDMA) system. Transmitter and receiver scheme of MC-DS-CDMA system using space-time codes is presented. Computer simulation shows that the performance of MC-DS-CDMA system using space-time codes is superior to the performance of conventional MC-DS-CDMA and MC-CDMA systems using space-time codes.
