美国苏威PEEK KT-880 CF30详解：

The transmission of information over frequency selectivedigital communications channels is subject to intersymbolinterference (ISI). Equalization has proven to be an effectivemeans for removing ISI. The commonly used approach em-ploys a known sequence of training symbols and the equalizercoefficients are then adapted by using some adaptive algorithmso that the output of the equalizer closely matches the trainingsequences by minimizing the mean-squares-error (MMSE)criterion. However, in many high data rate bandlimited dig-ital communications systems, the transmission of a trainingsequence results in a significant reduction in the effectivecommunication link data rate. Therefore, instead of using atraining sequence, only some statistical or structural propertiesof the transmitted and received signal can be exploited in ablind process to adapt the equalizer i.e. blind equalization.One of the simplest and the most effective blind equalizationschemes is the constant modulus algorithm (CMA) [1], [2],which uses constant modularity as the desired property ofthe output of the receiver. A great deal of research aboutconvergence behavior has been reported but a lack of com-prehension about the global convergence of these algorithmshas limited their utilization. Global convergence has beenproven under ideal conditions [1], [2], [3], [4] (e.g., noise-freeand doubly infinite equalizer) providing the inverse transferfunction of the channel. However, this assumption can beexcessive and the channel noise must be considered in thedesign of the equalizer. Recently, Zenget al.[5] have proposedinteresting results on the relashionships between blind andWiener receivers in the noisy case. They observe that if aWiener equalizer reaches an acceptable MSE performance,there exists a CM equalizer in its immediate neighborhoodwhich is approximately a scaled version of the Wiener receiver.
