I know this is the general syntax for random interleaver/deinterleaver
intrlvd = randintrlv(data,state)
deintrlvd = randdeintrlv(data,state)
But i am using matlab R2009a . The code at transmitter side is given below. At receiver i dont know how to use for randomdeinterleaver. How can i represent the data and state plz help me
I = randint(1,43200); % INFORMATION BITS
H = dvbs2ldpc(2/3);
l = fec.ldpcenc(H);
codeword = encode(l,I);
inter = randintrlv(codeword,64800);
hMod = modem.qammod('M', 256);
symbols = hMod.Constellation;
scatterplot(symbols);
