Abstract
In the high-speed wideband wireless communications, the duration of channel impulse response is about hundreds of symbol periods, which causes the convergence speed of blind equalizer to be slow. In this paper, a hybrid subband structure based blind equalizer is proposed to deal with the problem. The proposed blind equalizer effectively combines the subband decomposition technique with the sub-convolution method. And its convergence speed is faster than that of the traditional blind equalizer in the high-speed wideband transmission. On the other hand, since the down-sampling and the parallel processing of subband signals are used, the structure possesses lower computational complexity, which is beneficial to the real-time applications. Computer simulations are presented to illustrate the efficiency of the blind equalizer based on the new structure.
