Abstract :
A general folded encoding structure for multi-rate quasi-cyclic LDPC codes is proposed in this paper to implement LDPC encoder with the advantages of few resources consumption, adjustable parallelism and high coding rate. For the quasi-cyclic LDPC codes mentioned in this paper, folded encoding structure can provide high coding rate and save 66% of the resources compared with the traditional encoding structure.
