Design and Implementation of a Fast RS and QC-LDPC Cascade Encoder

In this paper, a novel design of RS+QC-LDPC cascade encoder is presented, furthermore, the based FPGA implementation of the encoder is introduced.The throughput of cascade encoder surpasses 2.25G bit/s with using several optimization techniques, such as duplex expansion QC-LDPC code, interleave coded and reasonable code length and code rate.
