摘要
针对WCDMA下行链路空时编码发送分集 (STTD)确定了基于最大比合并 (MRC)的分集接收方案 ,并对其进行了性能分析。数值分析结果表明 ,该方案在单天线RAKE分集基础上进一步增强多径分集效果 ,能较大地改善误码率性能和提高系统的抗衰落能力。
According to space time block coding based transmitting antenna diversity (STTD) in the WCDMA system,this paper presents a reception scheme based on maximal ratio combining (MRC).Results of the performance analysis show this scheme provides more benefit of diversity to overcome fading than the conventional single antenna RAKE receiver,and so gets better BER performance.
