一种新的宽带2FSK非相干解调器

讨论在低压配电网电力线高速数据通信信道下，宽带2FSK信号的最佳非相干解调问题。基于对信道统计特性的估计，提出了一种非相干最佳接收机的结构，可使接收机更好地适应低压电力线信道的时变特性。并给出了误码率公式以及最佳加权系数和误码率数值曲线。数值分析结果表明，设计的非相干2FSK最佳解调器的误码性能优于传统的非相干2FSK解调器。

A Novel Kind of Wideband 2FSK Non-Coherent Detector

Under the power line high speed data communication channel of low voltage power distribution network,the problem concerning the optimal non-coherent detection of wideband 2FSK signals is discussed in this paper.Based on the estimation of communication channel characteristic statistics,a kind of non-coherent optimal receiver structure is suggested.Also,this paper presents the error code rate formula,the optimal weighted coefficient and error code rate numeric curves.Numeric analysis results indicate that the error code performance of designed non-coherent 2FSK optimal detector is superior to that of the traditional non-coherent 2FSK detector.
