IMPLEMENTATION OF DIFFERENT DECODING TECHNIQUES FOR QUASI CYCLIC LOW DENSITY PARITY CHECK CODES (QC - LDPC)
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
This paper presents a different decoding techniques for Quasi - Cyclic (QC) Low Density Parity Check (LDPC) code. QC - LDPC code is proposed to reduce the complexity of the Low Density Parity Check code while obtaining the similar performance. The encoding and decoding processes of these codes are easy to simplify and implement. The algorithm used for encoding and decoding are based on matrices and implemented on MATLAB for simulation results. In this paper decoding technique QC - LDPC is introduced a nd compare the performance of LDPC and QC - LDPC. The decoding techniques is conducted by different algorithms such as Bit Flipping (BF), Belief Propagation (BP) Log, Belief Propagation (BP) Probabilistic (Prob), Belief Propagation (BP) Log Simple.
