convfilt.m

用BP神经网络实现的第三代移动通信CDMA多用户检测算法

function [convecr]=convfilt(filterout,truedata)
%decision
user1true=truedata(1,:);
user1data=filterout(1,:);
datanum=length(user1true);
num_of_err=0;
for i=1:datanum
   if(user1data(i)<0)
      decision=-1;
   else
      decision=1;
   end
   %If there is error,counter add 1
   if(decision~=user1true(i))
      num_of_err=num_of_err+1;
   end
end
%compute BER
convecr=num_of_err/datanum;
