Repetition code

This program is used to generate repetition code for the following specifications: number of bits =5, message bit value =1

function [G,H,x]=RepetitionCode(n,k,m)

//Repetition Codes

//n =block of identical 'n' bits

//k =1 one bit

//m = 1;// bit value = 1

I = eye(n-k,n-k);//Identity matrix

P = ones(1,n-k);//coefficient matrix

H = [I P'];//parity-check matrix

G = [P 1];//generator matrix 

x = m.*G; //code word

disp(G,'generator matrix');

disp(H,'parity-check matrix');

disp(x,'code word for binary one input');

endfunction

//Result

//-->exec('C:\Users\SENTHILKUMAR\Desktop\Communication_Toolbox\Digital_Communication\RepetitionCode.sci', -1)

//
