Soft Iterative Decoding for Overloaded CDMA
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006The probabilistic association algorithm (PDA) is proposed as a quasi-optimal solution for synchronous overloaded CDMA detection. Overloaded CDMA is useful in applications in which the band is a limited resource and more users are to be conveyed on the same channel.

Though coding theory suggests long error correcting codes chosen at random perform close to the optimum, the problem of designing good codes has traditionally been attacked by developing codes with a lot of structure, which lends itself to feasible decoders.

Algorithms to decode iterated codes when at least one of the "component codes" is majority decodable are given. The decoding algorithms allow the use of the decoders of the component codes and still make it possible to correct all error patterns guaranteed to be correctable by the minimum distance of the iterated code.

Decoder diversity architectures for finite alphabet iterative decoders
2014 48th Asilomar Conference on Signals, Systems and Computers, 2014We present a finite alphabet iterative decoders (FAIDs), a new type of decoders for low-density parity check (LDPC) codes, which outperform much more complex belief-propagation-based counterparts in the error floor region. The FAID variable node update is a simple Boolean map, and we show that by varying this map one can achieve a class of decoders ...

In this tutorial paper we present iterative algorithms which can be used for decoding of concatenated codes. The decoding operation is based on either a maximum a posteriori (MAP) algorithm or a Viterbi algorithm generating a weighted soft estimate of the input sequence.

Iterative decoding algorithm of lattices
Canadian Conference on Electrical and Computer Engineering 2004 (IEEE Cat. No.04CH37513), 2004The so-called min-sum algorithm for iterative decoding of low-density parity-check (LDPC) codes is generalized to decode lattices. An upper bound on the decoding complexity per iteration is derived, and for LDPC lattices constructed by Construction D' and using a nested sequence of LDPC codes, exact values for computational complexity are also given ...

Cross-entropy and iterative decoding
IEEE Transactions on Information Theory, 1998Summary: In this correspondence, the relationship between iterative decoding and techniques for minimizing cross-entropy is explained. It is shown that minimum cross-entropy (MCE) decoding is an optimal lossless decoding algorithm but its complexity limits its practical implementation.

Improvement of Shuffled Iterative Decoding
2006 IEEE Information Theory Workshop - ITW '06 Chengdu, 2006An improved version of shuffled belief propagation of iterative decoding of LDPC codes is proposed. The proposed scheme can speed up the convergence of iterative decoding. Simulation results verified our conclusions.

Adaptive iteration for fountain decoding
The Journal of China Universities of Posts and Telecommunications, 2010Abstract This article investigates fountain decoding combined with adaptive iteration algorithms in additive white gaussian noise (AWGN) channel. This paper introduces three adaptive iteration decoding strategies: Parity Check, cyclic redundancy check (CRC) and signal difference ratio (SDR) to fountain decoding to reduce the decoding complexity ...
