含有交织码编码与解码

a=randint(1,336);%a为1行360列的矩阵
T1=bianma(a);     %编码(120*7矩阵)
t1=jiaozhi(T1,4,7);
T2=zaosheng(t1,100);%加噪声得120*7
t2=jiaozhi(T2,7,4);
t3=reshape(t2,7,112)';
T3=jiucuo(t3);%对循环编码进行一位纠错解码
T4=reshape(T3,7,112);
T4=T4';%行列变换
A1=jiema(T4); %解码
a1=reshape(A1,336,1);
a1=a1';%行列变换，得到a1为纠错解码后的输出码
n=xor(a1,a)*ones(336,1); %n为误码个数
f=n/336 %f为误码率
