Blind Equalizer Based on Simulated Annealing Algorithm

Blind equalization is an adaptive equalization without resorting to a training sequence.The study is intended to overcome the detrimental effects of intersymbol interference caused by distortion of a communication channel.The object of this paper is to provide a practical introduction to blind equalization,which includes a description of the most widely referenced criterion—the maximum normalized cumulant criterion,a description and some discussion of simulated annealing algorithm.Finally,thesimulation of this algorithms is given.
