美国苏威PEEK ***-651 BK详解:
Channel- equalizer block diagram. The cascade channel-equalizer isknown as the global resp***e.the noise and the residual interference after filtering by theequalizer, respectively. In this paper, our approach differs fromwork on channel deconvolution because we assume that theresidual interference is not null at the equalizer output, ̄xn6= 0.So, the output of the equalizer can be writtenzn=sνan−ν+ ̄xn+wn(11)where the receiver gainsνis defined asCHHeν, andeνdenotes theνth unit row vector (contains only one non zerofor a particular value of delayν). The Kurtosis ofzncan beexpressed by Denote∗superscript as the complex conjugate operator. Inorder to obtain a closed-form for the equalizerC, using thegainsνwe derived the Schwarz inequality which allows us towrite。
