Hello. Your code is very messy and one cannot understand what you're trying to do. Again, the only thing you need to do is to generate an LDPC-coded bit sequence at the transmitter and add the decoder at the receiver. From what I have seen, you are changing other parts of the code, and that is why you are getting errors. If you want help, you need to be more specific about the problems you have.
