space time transmit diversity meaning in Chinese

空间时间发射分集

The analysis of the performance and its comparison to space time transmit diversity ( sttd ) are presented in this chapter . the link level simulations are performed . finally we discuss the effects of feedback delay and feedback error on the performance
第五章首先介绍了闭环发送分集的原理；接着对其性能进行了仔细的分析，完成了链路级仿真，并与开环发送分集进行了对比；最后讨论了反馈延迟、错误对性能的影响。
