soft_decision.asv

基于EMCA368国际标准的物理层超宽带协议的基本仿真程序,都是自己编写的

function [out]=soft_decision(data1,data2);
d(1)=(abs(data1-(-3-j*3)))^2+(abs(data2-(1+j)))^2;
d(2)=(abs(data1-(-3-j)))^2+(abs(data2-(1-j*3)))^2;

d(6)=(abs(data1-(-1-j)))^2+(abs(data2-(-3-j*3)))^2;
d(7)=(abs(data1-(-1+j)))^2+(abs(data2-(-3+j*3)))^2;
d(8)=(abs(data1-(-1+j*3)))^2+(abs(data2-(-3-j)))^2;
d(9)=(abs(data1-(1-j*3)))^2+(abs(data2-(3+j)))^2;
