Approaching Capacity at High-Rates with Iterative Hard-Decision Decoding [PDF]
, 2016 A variety of low-density parity-check (LDPC) ensembles have now been observed to approach capacity with message-passing decoding. However, all of them use soft (i.e., non-binary) messages and a posteriori probability (APP) decoding of their component ...

Iterative Decoding of Concatenated Codes: A Tutorial
EURASIP Journal on Advances in Signal Processing, 2005 The turbo decoding algorithm of a decade ago constituted a milestone in error-correction coding for digital communications, and has inspired extensions to generalized receiver topologies, including turbo equalization, turbo synchronization, and turbo ...

Approximate MIMO Iterative Processing with Adjustable Complexity Requirements [PDF]
, 2011 Targeting always the best achievable bit error rate (BER) performance in iterative receivers operating over multiple-input multiple-output (MIMO) channels may result in significant waste of resources, especially when the achievable BER is orders of ...

Decoding Schemes for FBMC with Single-Delay STTC
EURASIP Journal on Advances in Signal Processing, 2010 Orthogonally multiplexed Quadrature Amplitude Modulation (OQAM) with Filter-Bank-based MultiCarrier modulation (FBMC) is a multicarrier modulation scheme that can be considered an alternative to the conventional orthogonal frequency division multiplexing

Incidence structures from the blown-up plane and LDPC codes [PDF]
, 2011 In this article, new regular incidence structures are presented. They arise from sets of conics in the affine plane blown-up at its rational points. The LDPC codes given by these incidence matrices are studied. These sparse incidence matrices turn out to

Noncoherent iterative (turbo) decoding [PDF]
IEEE Transactions on Communications, 2000 Previously, noncoherent sequence detection schemes for coded linear and continuous phase modulations have been proposed, which deliver hard decisions by means of a Viterbi algorithm. The current trend in digital transmission systems toward iterative decoding algorithms motivates an extension of these schemes.

Finite alphabet iterative decoders for LDPC codes surpassing floating-point iterative decoders [PDF]
Electronics Letters, 2011 Introduced is a new type of message-passing (MP) decoders for low-density parity-check (LDPC) codes over the binary symmetric channel. Unlike traditional belief propagation (BP) based MP algorithms which propagate probabilities or log-likelihoods, the new MP decoders propagate messages requiring only a finite number of bits for their representation in ...

Understanding turbo codes: A signal processing study
Journal of Information and IntelligenceIn this paper, we study turbo codes from the digital signal processing point of view by defining turbo codes over the complex field. It is known that iterative decoding and interleaving between concatenated parallel codes are two key elements that make ...

Correcting Suboptimal Metrics in Iterative Decoders [PDF]
2009 IEEE International Conference on Communications, 2009 In this paper the issue of improving the performance of iterative decoders based on sub-optimal calculation of the messages exchanged during iterations (L-values) is addressed. It is well known in the literature that a simple-yet very effective-way to improve the performance of suboptimal iterative decoders is based on applying a scaling factor to the ...
