ABSTRACT: Based on understanding a set of Low-density parity-check codes recommended by CCSDS and
studying their encoding and decoding principles, we concentrate our experimental research on the encoding and
decoding of an (1280, 1024) LDPC code with code rate 4/5. Firstly, an encoder for this code is implemented by
using an FPGA device. Next, several decoding algorithms for the LDPC code over an additive white ...
