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 ...

An Iterative Unified Decoding for Decode-Quantize-Forward Relaying
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013This paper proposes a design strategy for decode- quantize-forward (DQF) relaying in which two relay nodes parallelly forward quantized a-posteriori loglikelihood ratio (LLR) after channel decoding. A primary focus is on cross correlation among quantized bits.

CONVERGENCE IMPROVEMENT OF ITERATIVE DECODERS
2006Iterative decoding techniques shaked the waters of the error correction and communications field in general. Their amazing compromise between complexity and performance offered much more freedom in code design and made highly complex codes, that were being considered undecodable until recently, part of almost any communication system.

Iterative Decoding of Iterative Clipped and Filtered OFDM Signal
IEEE Transactions on Communications, 2013A communication system with non-linear power amplifier (PA) is considered. We introduce three major performance criteria of the system: (i) power efficiency of the PA, (ii) spectral purity of the transmitted signal expressed by adjacent channel interference, and (iii) transmission performance expressed by mutual information or symbol error rate.

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.
