Blind Neural Network Equalization Algorithm Based on Orthogonal Wavelet Transform Fractionally Spaced Equalizer
摘要
Abstract
A new blind equalization algorithm of neural network based on orthognal wavelet transform fractionally spaced equalizer T/4-FSE-WT-FNN) is proposed to reduce the steadystate error and improve the convergence rate. Four sub-channels are used in the algorithm and neural network is adopted as the equalizer in each channel. Simultaneously, the equalizer input signal is carried out by the orthogonal wavelet transform and normalized. Compared with WTFNN, T/4-FSE-CMA and T/4-FSE-WT-CMA algorithms, the proposed algorithm has the characteristics of faster convergence, smaller steady-state error and lower root mean square error. The efficiency of the proposed algorithm is proved by simulation in underwater acoustic channels.关键词
