提出了一种频率选择性衰落环境下多输入多输出高速下行分组接入 (MIMOHSDPA)系统中chip级的空时均衡接收方案 ,以消除多天线和多码扩频传输时产生的严重的码间干扰和共信道间干扰 ;并推导出分数采样时的空时均衡接收机以进一步提高接收机性能 ,然后给出分析和接收信干噪比来设计最优权重 .ITUPedestrianA信道环境下的仿真结果验证了本文的分析和接收机优越的性能 .
This paper proposes a chip-level space-time balanced reception scheme in MIMO-MIMO system under frequency-selective fading environment to eliminate the serious code space caused by multi-antenna and multi-code spread spectrum transmission Interference and co-channel interference; and derive the space-time equalization receiver for fractional sampling to further improve the receiver performance, and then give the optimal weights for analysis and reception of SINR. Simulation results in ITUPedestrianA channel environment The analysis of this article and receiver superior performance.
