Hend A. Orabi, A. Zekry, G. Gomah . Implementation for Two-Stage Hybrid Decoding for Low Density Parity Check (LDPC) Codes. International Journal of Computer Applications. 80, 3 ( October 2013), 34-41. DOI=10.5120/13843-1669
Abstract
LDPC codes are gaining high attention in Channel Coding field these days. However, one of the main problems facing usage of these codes in communication systems is the high complexity decoding scheme that results in high decoding delay. Such delay is not acceptable in some applications that depend on time such as video transmission. This paper presents hardware implementation technique for Two-Stage Hybrid decoder resulting in better complexity and delay. Also, it shows comparison between soft, hard and hybrid decoding techniques in terms of memory usage, and delay time as to be used for real implementation for some applications such as DVB-S2.
