Zero Forsing Equalizer
Zero Forcing Equalizer is a type of linear equalizers used to
%combat ISI(inter symbol interference). This codes is a demostration of a
%simple implemenation of Zero Forcing Equalizer using MatLab tools.
% A typical channel is model in discrete domain as:
%%%%%% y[n]=h[n]*x[n]+z[n]
% where y[n] is channel output, x[n] is channel input, h[n] is channal
% impulse response, z[n] is AWGN nosise
% We can convert channel to frequency domain as follows:
% Y(f)=H(f)X(f)+Z(f)
% Zero-forcing equalizer multiplies Y(f) by inv(H(f))
% inv(H(f))Y(f)=X(f)+inv(H(f))Z(f)
% thus we essancially get an ISI free channel.
% The drawback is that noise is enhance
