Hi

I need an efficient .m file for designing S-Random Interleavers.
I wrote one, but it did not converge for L24 & S.

Thanks

I know this post has been ages. But in case anyone out there is still
searching, hope this piece of code would help:

x = 1:10 % Original data
nrows = 3; slope = 2; % Interleaver parameters
D = nrows*(nrows-1)*slope; % Delay of interleaver/deinterleaver pair
x_padded = [x, zeros(1,D)]; % Pad x at the end before interleaving.
x_intrlv=convintrlv(x_padded,nrows,slope);
xintrlv=x_intrlv(x_intrlv~=0)

I was looking for an s-random interleaver myself and found little help on
coding. But managed to solve to fit my needs with this small piece of code.
Hope this could help!
