Hello
I have inverted the bch output just as you suggested but still the same "multichannel operation is not supported" error. here is a bit of my code so you might take a look
thank you.
hStr=RandStream('mt19937ar','seed',654321);
BBFrame=randi(hStr,[0,1],32208*k,1);
BCHFEC=step(EncoderBCH,BBFrame);
BCHFEC=BCHFEC';
FECFrame=step(hEnc,BCHFEC);
hInt = comm.BlockInterleaver(permVec);
IntData = step(hInt, FECFrame);
hMod = comm.PSKModulator(M, 'PhaseOffset',pi/16);
Msg_tx = step(hMod, IntData);
Msg_tx = rectpulse(Msg_tx,NSAMP);
EbNo=5;
snr=EbNo+10*log10(H)-10*log10(Nsamp);
hAWGN = comm.AWGNChannel('NoiseMethod', ...
'Signal to noise ratio (SNR)','SNR',snr);
noisy_msg = step(hAWGN, Msg_tx);
noisy_msg = intdump(noisy_msg, Nsamp);
hDemod = comm.PSKDemodulator(M, 'PhaseOffset',pi/16);
Msg_rx = step(hDemod, noisy_msg);
hDeInt = comm.BlockDeinterleaver(permVec);
FECFrame_rx = step(hDeInt, Msg_rx);
BCH_rx = step(hdec, FECFrame_rx);
BCH_rx =BCH_rx ';
BBFrame_rx = step(DecoderBCH, BCH_rx);
