Hi M_all
I need the paper for Understanding of Encoder and Decoder of LDPC. As you mentioned in you message (msg given below.)that u have a paper. also if you can send me your BS Project thesis to my understanding in LDPC.
I am waiting for your reply.
My BS project was in LDPC. in some case of LDPC code, encoding is very easy. in this case LDPC code generate by just LFSR(Linear Feedback Shift Register) like cyclic code. In this case some kind of Geometry code (EG and PG) are LDPC.
But decoding ?
LDPC codes have 3 method for decoding.
1- using Majority Logic gate 2- Bit Flipping 3- Belief Propagation or Sum Product(Message Passing).
Method 1 is very easy but not very good performance.
Method 2 is the modest method in complexity and performance.
Method 3 is very complex but very good performance.
I suggest method 2 for hardware implementation.
I have 1 good paper for all 3 method. tell me if u want.
