摘要

研究了在双射线选择性瑞利衰落信道上传输的无编码正交相移键控(QPSK)信号的误差性能。假设一个具有完美信道状态信息的维特比接收机。对于矩形基带脉冲，发现两个到达射线之间的相对延迟引入了分集效应，这有助于提高比单射线，频率非选择性衰落信道的误差性能。

Bit-error probability of uncoded QPSK transmitted over a 2-ray frequency selective Rayleigh fading channel

The authors study the error performance of uncoded quadrature phase shift keyed (QPSK) signals transmitted over a two-ray frequency selective Rayleigh fading channel. A Viterbi receiver with perfect channel state information is assumed. For a rectangular baseband pulse, it was found that the relative delay between the two arrival rays introduces a diversity effect which helps to improve the error performance over that of a one-ray, frequency non-selective fading channel.<>
