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...

Achieving near-capacity performance on multiple-antenna channels with a simple concatenation scheme
This paper proposes a capacity-approaching, yet simple scheme for multi-input multiple-output (MIMO) channels. The proposed scheme is based on a concatenation of a mixture of short...
