Abstract:

A hybrid sub-optimal technique has been proposed in this paper for decoding the LDPC codes, which delivers a better performance. The two decoding algorithms namely, the Sum Product Algorithm (SPA) and One Step Majority Logic Decoding Algorithm (OSMLGD) are pooled together to accomplish decoding of LDPC codes. Also the two algorithms are implemented exclusively in order to compare the performance. The error correction capability is compared by plotting the Bit-Error Rate v/s SNR graph and the computational complexity is also compared. © 2016 IEEE.
