- Performance of M ary orthogonal direct sequence code division multiple access ( DS-CDMA) signals over multipath Rayleigh fading channel with noncoherent RAKE receiver is examed. Two maximum selection diversity reception schemes, maximum signal to noise ratio selection and muximum output selection, are considered.
研究了随机M进制正交码直接序列扩频码分多址信号经过多径瑞利频率非选择性衰落，在非相干RAKE接收机中采用最大输出信噪比选择或最大输出选择分集接收时系统的性能； - Some new developments in CDMA system coding filed are focused on. Finally multipath signal reception techniques of CDMA system based on orthogonal complementary codes are demonstrated.
文章追踪了CDMA系统编码领域的最新动态，并在最后给出了正交全补码的CDMA系统的多径信号接收技术。 - However, multipath components can be resolvable due to the autocorrelation of the spread spectrum signal, thus the optimal receiver equals coherent RAKE reception, i.e. maximum ratio combining the independent components which endure flat fading or frequency non-selective fading.
但是利用扩频信号的自相关特性，可分辨多径可以被有效分离，最优接收机等效为对多个具有独立平坦衰落信道（或频率非选择性信道）特性的多径信号进行最大比合并，即相干RAKE接收。 - In the frequency-selective multipath fading scenario, Rake reception was considered, and an approximation based on perturbation theory was derived.
在频率选择性多径衰落信道环境中，接收端采用Rake接收机时，推导出了基于微扰理论近似法的系统误比特率公式。
