Implementation of a new LDPC encoder for CCSDS specification based on FPGA

摘要

A new Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) encoder based on type I Rotate-Left-Accumulator (RLA) circuits is designed for the Consultative Committee for Space Data Systems (CCSDS). The proposed encoder is serial-input and serial-output. It can reduce the power consumption and save memory resource. FPGA simulation shows its feasibility.
