摘要: 本文提出了一种适用于TDD/DS-CDMA下行链路的空间-时间预RAKE系统。该系统能实现空间的选择性发送和时间的预RAKE发送。然后给出了单用户和多用户情况下的该系统性能分析,并讨论不同信道参数(角度扩散,Doppler频率和突发帧长等)对系统性能的影响。Abstract: This paper proposes a space-time pre-RAKE system for the downlink in TDD/DS-CDMA. The system realizes space-selective transmission and temporal pre-RAKE. Performance analysis in single- and multi-user environment is presented and the relation between system performance and channel parameters (angle spread, Doppler frequency and burst frame size) is discussed.
