Design of LDPC decoder using message passing algorithm
Prerana Dhanorkar, Monica Nilesh Kalbande · 2017
Low density parity check (LDPC) codes are most favorable error-correcting codes and also in terms of high coding gain, high throughput and low power dissipation LDPC code is advantageous. In this paper, for designing LDPC decoder the Min Sum Algorithm for decoding the LDPC codes is suggested. Min Sum algorithm is belong to soft-decision decoding techniques The hardware implementation of check node and variable node using a traditional technique based on HDL code is very complex and time consuming. Here a new approach for designing of LDPC decoder using Simulink modelling have been proposed. For check node and variable node the hdl code have been generated using the Simulink hdl coder in matlab.
