摘要 分析了在WCDMA系统的基站中采用含自适应阵列天线的空时RAKE接收机的性能。在建立了WCDMA信道信号模型的基础上 ,分析了噪声和干扰的统计特性 ,给出了输出误码率的表达式 ,并对不同角度扩展情况下的数值仿真结果进行了讨论。 This paper analyzes the performance of Space-time RAKE Receiver at the base-station of WCDMA System which employing adaptive antenna array.Based on the model of WCDMA channel and received signal,the statistics of noise and interference is analyzed and the expressions of output bit error rate(BER) are derived.At last,the results of numerical simulations in the case of different angle spread are discussed.
