function int_matrix=Interleaver(conv)

%This is the Block Interleaver.
%The Block Interleaver is a 24 rows by 16 columns array matrix
%It reads in a data bit stream row-by-row then output column-by-column

%Define array matrix

int_matrix1=zeros([24,16]);

nrows=24;
ncolumns=16;

%Fill in the empty matrix row by row,eventually

for nr=1:nrows
     for nc=1:ncolumns
     
     int_matrix1(nr,nc)=conv(nc+((nr-1)*ncolumns));
     end
end

%output data bits column-by-column

int_matrix=int_matrix1(:)';
