APPLICATIONS OF DECODING DUAL CODES TECHNICQUE IN LDPC DECODING

Abstract

This paper presents the basic of the decoding method using the dual decoding techniques, applications with the code Haming, code LDPC ... This approach allows the use of iterative decoding techniques combined with the use of the equyvalent matrix H  and decision-making techniques based on the weight of the syndrome when decoding. Simulation results performed on a Gaussian channel model and fading channel using the BPA-EH algorithm (Belief Propagation Algorithm Based on Equivalent Parity Check Matrix H) result in significant improvements in decoding behavior and Shorten time decoding compared to traditional BPA algorithms.
