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...

Low-Complexity, Low-Memory EMS Algorithm for Non-Binary LDPC Codes
— In this paper, we propose a new implementation of the EMS decoder for non binary LDPC codes presented in [7]. A particularity of the new algorithm is that it takes into account...

Low-complexity decoding for non-binary LDPC codes in high order fields
In this paper, we propose a new implementation of the Extended Min-Sum (EMS) decoder for non-binary LDPC codes. A particularity of the new algorithm is that it takes into accounts...
