Abstract :
In this paper we evaluate the performance of Gallager-B algorithm, used for decoding low-density parity-check (LDPC) codes, under unreliable message computation. Our analysis is restricted to LDPC codes constructed from circular matrices (QC-LDPC codes). Using Monte Carlo simulation we investigate effects of different code parameters to coding system performance, under binary symmetric communication channel and independent transient faults model.
