Improved LDPC Decoding Speed Using Past Decoding Information

The Pan-Hellenic Conference on Electronics and Telecommunications - PACET 2015, Ioannina, Greece, May 2015.

Abstract: In this work, a new LDPC decoding architecture for DVB-S2 is proposed. Based on the traditional LDPC decoding algorithm, low-pass filtering on probability decisions is used in order to suppress radical changes. This results in improved performance gain either as decreased number of required iterations or as higher error correction capability under severe channel conditions. Simulation results for different modulation schemes are used to demonstrate the improved performance of the proposed approach.
