Abstract: Multi-user MIMO-CDMA is new technology in MIMO research areas.Capacity and BER performance can be remarkably enhanced in MIMO-CDMA system.Because of high complexity for DSP realization of MIMO system，antenna selection is low-complexity alternative for real MIMO-CDMA system.Multi-user MIMO-CDMA antenna selection Sub-system is introduced in the paper.A simulate Model based on frame structure of multi-user MIMO-CDMA antenna selection sub-system for DSP is designed.Performance in different selection rules，such as MBER，MMI and MNP，is analyzed and compared.Evaluation of simulation result is given.
Key words: MIMO-CDMA, antenna selection, Least Squares（LS） estimation
摘要： 多用户MIMO-CDMA是MIMO技术领域研究的最新成果，MIMO-CDMA系统可以显著地提高系统的容量和BER性能。但系统复杂度高，而天线选择技术可以大大降低MIMO-CDMA系统实现复杂度。设计了一种基于帧结构的MIMO-CDMA接收端子选择系统仿真平台，分析和比较了在MBER、MMI和MNP等不同选择准则条件下的系统性能，并对仿真结果进行了评价。
