Decoding real-field codes by an iterative Expectation-Maximization (EM) algorithm
In this paper, a new approach for decoding real-field codes based on finding sparse solutions of underdetermined linear systems is proposed. This algorithm iteratively estimates...

Iterative Decoding of Concatenated Channel Coding and Trellis Shaping Based on Markov Model
—The trellis shaping (TS) is an effective technique not only for average power reduction of high-order QAM signals, but also for peak power reduction of band-limited single-carri...

On Some New Approaches to Practical Slepian-Wolf Compression Inspired by Channel Coding
We introduce three new innovations for compression using LDPCs for the Slepian-Wolf problem. The first is a general iterative Slepian-Wolf decoding algorithm that incorporates the...

Connected filtering by reconstruction: Basis and new advances
Openings-by-reconstruction are the oldest connected filters, and indeed, reconstruction methodology lies at the heart of many connected operators such as levelings. Starting out ...

A New Powerful Scalable Generic Multi-Standard LDPC Decoder Architecture
We propose a new powerful scalable generic parallel and modular architecture well suited to LDPC code decoding. This architecture template has been instantiated in the case of the...
