symbol_deci输出判决.m

这是个扩频仿真的有关程序

function symbol=symbol_deci(symbol_rec,d)

mapping=[d,j*d,-d,-j*d];

% % numoferr=0;
% for i=1:length(symbol_rec),
    for k=1:4
        metrics(k)=abs(symbol_rec-mapping(k));
    end;
    
    [min_metric decis]=min(metrics);
    
%     if (mapping(decis)~=Source_Data(i)),
%         numoferr=numoferr+1;
%     end;
    symbol=mapping(decis);
% end;
