Hello Bahman
I observed that its when i use "hEnc = comm.LDPCEncoder(H); and
hDec = comm.LDPCDecoder(H);" that the decoder introduces errors. I used this because I got an error message which I could not understand while using the following you recommended:
henc = fec.ldpcenc(H);
hdec = fec.ldpcdec(H);
hdec.DecisionType = 'Hard decision';
hdec.OutputFormat = 'Information part';
hdec.NumIterations = 50;
here is the error message I got, which I have since been unable to resolve:
Error using tf (line 293)
The values of the "num" and "den" properties must be row vectors or cell arrays of row
vectors, where each vector is nonempty and containing numeric data. Type "help tf.num" or
"help tf.den" for more information.
Error in step (line 97)
sys = tf(a,b);
Error in wild (line 42)
BCHFEC=step(henc,BBframe);
