摘要

分析了存在衰落和脉冲噪声的部分RAKE接收机。推导了脉冲衰落信道的最大似然PRR，得到了复杂度较低的次优PRR。数值结果表明，当噪声是脉冲噪声时，针对脉冲噪声设计的PRRs比针对高斯环境优化的PRRs性能有改善。结果表明，次优PRR与最佳PRR的性能基本一致。

Partial RAKE receivers for weak signals in impulsive fading environment

The partial RAKE receiver (PRR) is analyzed in the presence of fading and impulsive noise. The maximum likelihood PRR for impulsive, fading channel is derived, and a suboptimum PRR with reduced complexity is obtained. It is shown from numerical results that, when the noise is impulsive, the PRRs designed for impulsive noise offer performance improvement over those optimized for Gaussian environment. It is observed that the suboptimum PRR exhibits almost the same performance as the optimum PRR.
