| 摘 要： | 空时分组码(Spce—Time Block Coding)是目前研究发送分集(Transmit Diversity)技术的一个热点。针对TD—SCDMA系统的MIMO(Multiple-Input Multiple-Output)信道，将天线子集选择技术与空时分组码(Spce—Time Block Coding)相结合，进一步提升了发送分集的误码率性能。通过理论分析对此方案的进行了性能评估，表明天线选择技术对空时分组码(STBC)的性能有较大的改善。

| Abstract: | Space-time block coding is an attractive technique today. In this paper the authors combine optimal antenna sub-set selection technique with space-time block coding in TD-SCDMA system to boost the performance of transmit diversity. To evaluate the scheme over MIMO channel, theoretical analysis is made which shows that considerable improvement in average BER is achieved. |
