A Blind Identification and Equalization Algorithm of IIR Channel Based on Oversampling
Zhao Le-jun · Jisuanji fangzhen · 2009
A blind identification and equalization algorithm of communication channel is proposed.The channel is modeled as an IIR channel and the output of the channel is oversampled.The AR coefficients and MA coefficients are identified independently.It decomposes the channel into many subchannels in order to use more information about the unknown channel and improve the identification precision when it identifies the MA coefficients.The algorithm does not need the channel information and the statistical information on the input signal,so it is widely applicable.Simulation results show good performance of the proposed algorithm.
