mud.m

此程序为DS-CDMA链路中加入基于子空间的PASTd多用户检测方法。系统中采用m序列阔频

function [ich10,qch10]=mud(ich9,qch9,MUDmode,attn,A,code)
switch MUDmode
    case 1
        ich10 = ich9;
        qch10 = qch9;
    case 2
        R=(code*code')/7;
        ich10 = inv(R)*ich9;
        qch10 = inv(R)*qch9;
    case 3
        R=(code*code')/7;
        ich10 = inv(R+attn(1)^2*inv(A)^2)*ich9
        qch10 = inv(R+attn(1)^2*inv(A)^2)*qch9
    
end
