Abstract:
This paper presents the stochastic gradient estimation,which adds the noise in the channel to the gradient.Based on the correlation coefficient,an analysis is made of the effect of the stochastic gradient estimation on the blind equalization algorithm.Theoretical research shows that the stochastic gradient estimation lead to the deviation of the weight,which determines the size of the residual error.
