This paper presents the FPGA implementation of a number of popular decoding algorithms for a regular rate-1/2 low density parity check code with block length 504 bits. The so-called min-sum (MS) algorithm and two of its variants, known as MS with successive relaxation (SR-MS) and MS with unconditional correction (MS-UC), are implemented. We implement the algorithms on a Xilinx XC2VP100 FPGA device...
