LDPC codes are gaining greater importance in the applications requiring efficient and reliable transfer of information over communication channel. LDPC codes are innovative techniques which play a significant role in satellite communication, CDMA, Bluetooth etc. where the main purpose is to achieve the reliable data transmission maintaining efficiency, quality and minimum bandwidth. Thus, in the present paper, an effort is made on FPGA implementation of LDPC decoding algorithm using Simplified Sum Product Algorithm (SSPA) technique to obtain better efficiency with lesser error rate. The SSPA algorithm is verified in MATLAB for different parity check matrix combinations. Then this is coded in HDL and implemented in real time, integrating with FPGA using Artix-7.
