i want ask about tap in equalizer MMSE
why equalizer use tap 2M+1
and i find program MMSE equalizer
this is the program
% Channel model, multipath channel
nTap = 3;
ht = [0.2 0.9 -0.3];
L = length(ht);
hAutoCorr = conv(ht,fliplr(ht));
hM = toeplitz([hAutoCorr([3:end]) zeros(1,2*kk+1-L)], [hAutoCorr([3:end]) zeros(1,2*kk+1-L) ]);
why ht (multipath) have 3 number?????
and about matrix toeplitz, why start with number 3-end????
please help me???
