that led on from the work on Turbo codes, MacKay could now show that Low Density Parity Check (LDPC) codes could be decoded in a similar manner to Turbo codes, and may actually be able to beat the Turbo codes [6]. As a review, this paper will consider both these classes of codes, and compare the performance and the complexity of these codes. A description of both classes of codes will be given. I. Turbo Codes

the resurgence of interest in LDPC codes after over 30 years since Gallager’s work.4 LDPC codes based on non-regular graphs, called irregular LDPC codes, rose to prominence beginning in the work of Luby et al [16, 17] (studying codes based on irregular graphs was one of the big conceptual leaps made in these works).

Parity Check (LDPC) codes. Building on the increased understanding on iterative decoding and probability prop-agation on graphs that led on from the work on Turbo codes, MacKay could now show that Low Density Parity Check (LDPC) codes could be decoded in a similar man-ner to Turbo codes, and may actually be able to beat the Turbo codes [6].

Lu Block-LDPC Codes vs Duo-Binary Turbo-Codes for European Next Generation Wireless Systems 2008-08-06 The HNS LDPC code is a 61440-bit block size and intended to run up to about 100 Mbps. It utilizes an outer BCH code to reduce complexity. It was selected because the performance was superior to the candidate Turbo Codes and the complexity met the requirements. This is an example bipartite graph for an irregular LDPC code.
