Turbo Equalization With Irregular Turbo Codes [PDF]
2007 4th International Symposium on Wireless Communication Systems, 2007 We analyze a turbo equalization system that combines maximum a posteriori probability (MAP) equalization with irregular turbo codes. Our goal is to approach the information capacity limit for severe inter-symbol interference (ISI) channels. To this end, we optimize the degree profile of irregular turbo codes by maximizing the minimum distance between ...

On Maximum Contention-Free Interleavers and Permutation Polynomials over Integer Rings [PDF]
, 2005 An interleaver is a critical component for the channel coding performance of turbo codes. Algebraic constructions are of particular interest because they admit analytical designs and simple, practical hardware implementation. Contention-free interleavers

Recurrent neural network based turbo decoding algorithms for different code rates
Journal of King Saud University: Computer and Information Sciences, 2022 Application of deep learning to error control coding is gaining special attention and neural network architectures on decoding are approached to compare with conventional ones. Turbo codes conventionally use BCJR algorithm for decoding.

Quantum Serial Turbo Codes [PDF]
IEEE Transactions on Information Theory, 2008 We present a theory of quantum serial turbo-codes, describe their iterative decoding algorithm, and study their performances numerically on a depolarization channel. Our construction offers several advantages over quantum LDPC codes. First, the Tanner graph used for decoding is free of 4-cycles that deteriorate the performances of iterative decoding ...

Multi-level Turbo Decoding Assisted Soft Combining Aided Hybrid ARQ [PDF]
, 2010 Hybrid Automatic Repeat reQuest (ARQ) plays an essential role in error control. Combining the incorrectly received packet replicas in hybrid ARQ has been shown to reduce the resultant error probability, while improving the achievable throughput.

Comparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes [PDF]
IEEE Transactions on Wireless Communications, 2002 Turbo equalizers have been shown to be successful in mitigating the effects of inter-symbol interference introduced by partial response modems and by dispersive channels for code rates of R/spl les/ 1/2. We comparatively studied the performance of a range of binary phase-shift keying turbo equalizers employing block-turbo codes, namely Bose-Chaudhuri ...
