A fast BER evaluation method for LDGM codes. (English) Zbl 1202.94005
Summary: Low-density generator matrix (LDGM) codes have recently drawn researchers’ attention thanks to their satisfying performance while requiring only moderate encoding/decoding complexities as well as to their applicability to network codes. In this paper, we aim to propose a fast simulation method useful to investigate the performance of LDGM code. Supported by the confidence interval analysis, the presented method is, for example, \(10^{8}\) times quicker than the Monte-Carlo computer simulation for bit-error-rate (BER) in \(10^{ - 10}\) region.
