| 摘 要： | 分析了最大比合并(MRC)二维Rake(2D-Rake)接收机,在相关频率选择性Nakagarnl衰落环境中的平均误比特率(BER)特性。推导了在任意衰落环境中,存在多个共信道干扰的多天线多Rake抽头接收机的信干噪比(SINR)和BER的闭式表达式。文中还进一步说明了角度扩展、天线间隔、空间和时间分集阶数、平均到达角度、平均路径强度以及衰落程度对2D-Rake接收机BER性能的影响．

| Abstract: | The paper presents the average bit error rate (BER) of a maximal ratio combining (MRC) two-dimensional (2D)-Rake receiver in a correlated frequency selective Nakagami-fading environment. We derived closed-form expressions of the signal-to-interference-and-noise ratio (SINR) and BER for the receiver with multiple correlated antennas and multiple Rake fingers in arbitrary fading environments in the presence of multiple co-channel interferences. The effects of angular spread, antenna spacing, spatial and temporal diversity order, mean angle-of-arrival, average multi-path strength and fading severity on the BER performance of the 2D-Rake receivers are all illustrated. |
