摘　　要：本文基于不可分离多径瑞利衰落信道,假定各径之间的时延已根据高分辨算法正确估计且不考虑多普勒的情况下,根据卡亨南定理得到一组正交基,进而进行去相关运算,从而得出了一种非相干最佳二元检测结构,最后对此检测结构进行了误码分析和仿真。This paper, which is based on unresolved multipath Ricean fading channels, is first supposed that the delay of each path has been well estimated through high resolution arithmetic and the Doppler effect is ignored, then based on Karhunen theory it gives a group of orthogonal bases and use it in a decorrelation calcuation , and thus it gives a structure for noncoherent optimal binary detection. In the last part of this paper, it shows the BER analysis and emulation of this structure.
