%this declares the global variables for the zero forcing receiver
%these variables will be local to all zeroforcing files(i.e. unseen by
%any other sections of code without zforce in the title)
%
%
%user	:	choosen user to demodulate
%delay	:	choosen delay to demodulate 
%delta	: 	optimal delay for all users
%f	:	desired equalizer for specified user and delay
%F	:	matrix of mmse equalizers
%M	:	Matrix of mse for all users and delay
%achv_BER	:	BER achieved after simulation
%achv_mean_sqer	:	achieved mean squared error	
%s_hat	:		vector of soft decision output
%squer	:		vetor of error (s_hat-s)
