| Abstract: | Blind equalizer plays an important role in communication system,but in general it exhibits very slow convergence rates and ill convergence.In this paper,first new class of stochastic gradient algorithm is analyzed,secondly a convex cost function and a normalization step size is presented,they improve error performance surface that are not guaranteed to be unimodel,and convergence speed in the vicinity of a saddle. |
