GSM的仿真源码,比较详细,分为模块和全信道两部分

%交织编码和反织编码的加突发噪声后的测试
echo off
clear all
close all
%突发间隔
N_Interval=80;
%突发长度
N_Length=10;
C=round(rand(1,456*3));%产生一个随机码字序列
CC=C;
u=INTER_WEAVE_8(C);%进行交织编码
Noise=BurstNoise(N_Interval,N_Length,length(u));%加突发噪声
Noise1=BurstNoise(N_Interval,N_Length,length(CC));
u=mod(u+Noise,2);
CC=mod(CC+Noise1,2);
D=COUNTER_WEAVE_8(u);%反交织
sig_err_rate=(length(find(D~=C)))/length(C)
sig_err_rate1=(length(find(CC~=C)))/length(C)
