debchcode.m

自己年编写的matlab中bch码的仿真程序。有编码和译码2个主程序

 g=[1 0 0 1 1 0 0 0 0 0 0 0 0 0 0];
 H=[1 1 1 1 0 1 0 1 1 0 0 1 0 0 0;0 1 1 1 1 0 1 0 1 1 0 0 1 0 0;0 0 1 1 1 1 0 1 0 1 1 0 0 1 0;1 1 1 0 1 0 1 1 0 0 1 0 0 0 1];
 HT=H.';

load('out.txt','-ascii');
 for i=1:15
     dbch1(i)=out(2*i-1);
     dbch2(i)=out(2*i);
 end

 bch1=correctcode(dbch1,g,HT);
 bch2=correctcode(dbch2,g,HT);
  
 for i=1:11
     m1(i)=bch1(i);
     m2(i)=bch2(i);
 end
