Abstract
In this paper we deal with the problem of the implementation of the simplified iterative decoding algorithms of Low Density Parity Check codes (LDPC). These algorithms correspond to a simplified version of the belief propagation algorithm (BP) in the logarithmic domain. Knowing that the Self Adjustable Offset Min Sum Algorithm (SAOMSA) algorithm allows a calculation complexity reduction and improve the performance, we suggest the use of the horizontal-shuffled scheduling instead of the usually used flooding. In the case of WiMAX standard, results show an increase of the convergence speed, which approaches the BP algorithm.
