acso.m

该文件夹中的SC_TurboIC_MIMO_0524.m是将我turbo的编译码模块替换原来B3G系统中的turbo编译码模块而重新得到的. 定点仿真得,在比特信噪比>=0.5db时,经过一次

function   metric=ACSO(metric1,metric2,Gsubadd);

sum1=metric1+Gsubadd;
sum2=metric2-Gsubadd;

delta=sum1-sum2;
correctfactor=log(1+exp(-(abs(delta))));

if(delta>=0)
    metric=sum1+correctfactor;
else 
    metric=sum2+correctfactor;
end
