Low complexity, flexible ldpc decoders

Abstract — The design and implementation of a flexible LDPC decoder able to cope with different codes, is gathering an increasing interest in the scientific community. Roughly speaking, a flexible decoder exhibits the remarkable ability of being able to decode different codes resorting to the same hardware. In this paper we present a novel decoder architecture specifically devised to present an high flexibility and to being able to properly trade-off decoding performances with reconfigurability and overall system complexity.
