Description: Software for Low Density Parity Check Codes Radford M. Neal Version of 2006-02-08. This collection of programs and modules, written in C, is intended to support research and education concerning Low Density Parity Check (LDPC) codes. (Note, however, that the copyright notice no longer restricts use to these purposes). These codes were invented by Robert Gallager in the early 1960's, and re-invented and shown to have very good performance by David MacKay and myself in the mid-1990's. The decoding algorithm for LDPC codes is related to that used for Turbo codes, and to probabilistic inference methods used in other fields. Variations on LDPC and Turbo codes are currently the best practical codes known, in terms of their ability to transmit data at rates approaching channel capacity with very low error probability.

Description: Turbo码，LDPC码（低密度奇偶校验码）均具有接近Shannon限的性能，
是目前便译码研究的热点。Turbo码在低信噪比情况下的性能优于其它各种编码
方式。而LDPC码的描述简单，具有较大的灵活性，当码长足够长时具有比Turbo
码更为良好的性能，其译码复杂度低于Turbo码。-Turbo code, LDPC code (LDPC) all have close to Shannon limit performance, it is the firm' s research focus. Turbo codes at low SNR is superior to other kinds of encoding. The simple description of LDPC codes with greater flexibility, when code length is long enough, have a much more favorable than the Turbo code performance, its decoding complexity than Turbo codes.

Description: This book includes BCH codes, Reed–Solomon codes, convolutional codes, finite-geometry
codes, turbo codes, low-density parity-check (LDPC) codes, and product codes.
However, the title has a second interpretation. While the majority of this book is
on LDPC codes, these can rightly be considered to be both classical (having been
first discovered in 1961) and modern (having been rediscovered circa 1996)
