Research on Parallel Convolutional LDPC Code based on Random Interleaver

摘要

Starting from pseudo-random interleaver and parallel convolution respectively, this paper has proposed a simple and fast LDPC encoding method without the loss of BER performance. When we use S-random interleaver, it has a good adaptation in both Gaussian noise channel and Rayleigh fading channel. And it can conduct random pre-encoding directly and does not need to look up for 4-cycles. Even if the number of iterations is low, its performance also remains stable.
