%FUNCTION 2.2 : "cp0201_repcode"
%
%Introduces a repetition code for the stream of 'bits' in input
%'Ns' identical binary values are generated from the same bits
%'repbits' represents the output binary sequence
function [repbits]=cp0201_repcode(bits,Ns)
%-------------------------------------------------
%Step One - Introduction of the repetition code
%-------------------------------------------------
numbits=length(bits);
temprect=ones(1,Ns);
temp1=zeros(1,numbits*Ns);
temp1(1:Ns:Ns*(numbits-1)+1)=bits;
temp2=conv(temp1,temprect);
repbits=temp2(1:Ns*numbits);
