Hi there, I am working with T/2 fractionally spaced equalizer. Here is what I am thinking about the problem. Suppose my even phase channel is h_e[n] of 10 taps and my odd phase channel is h_o[n] of 10 taps as well. Then, my even phase equalizer is g_e[n] of, let's say, 20 taps and my odd phase equalizer is g_o[n] of 20 taps as well. For simplicity, let's say the equalizer g_e[n] is obtained from h_e[n] using the MMSE criterion, and g_o[n] is obtained from h_o[n] using the MMSE criterion. So, the even phase combined channel is h_e convolved with g_e, and the odd phase combined channel is h_o convolved with g_o. Is there any problem with my T/2 spaced equalizer? Also, I think I can treat my T/2 spaced equalizer as a 2-receive-antenna equalizer with receive diversity (only that the two receive antennas are correlated). So, I expect T/2 spaced equalizer should have performance 1) better than T spaced equalizer with a single receive antenna 2) worse than T spaced equalizer with 2 receive antennas Is it right? Thanks. If you can also point to me some good reference, it is greatly appreciated.
