基于通道均衡的频域除法研究
A Study on Frequency-domain Division Based on Channel Equalization
摘要
Abstract
In frequency-domain channel equalization, one of the most crucial technologies is to seek the response of an equalization filter. AccordinS to the relation between the circular convolution in the time domain and the DFT product in the frequency domain,it is referred that two classes of algorithms on frequency-domain division in channel equalization, one class is time-domain algorithms which include an algorithm to seek the pseudo-inverse of a circular matrix and another algorithm to seek the deconvolution by circular convolution , the other is a frequency-domain algorithm having the least MSRe with matrix form. Accordinfl; to the error with the convolution between the filter to be emended and the corresponding equalization filter approximating the reference filter, the validity of the above algonthms is tested. The experimemal results shows that the frequency-domain algonthm having the least MSRe with matrix form excels those two time-domain algorithms in both approximation degree and real time.关键词
