Optimization of symbol mappings for bit-interleaved coded Modulation with iterative decoding
We investigate bit-interleaved coded modulation with iterative decoding (BICM-ID) for bandwidth efficient transmission, where the bit error rate is reduced through iterations between a multilevelExpand

Amplify-and-forward with partial relay selection
This letter offers a statistical analysis of the basic two-hop Amplify-and-Forward link, where the relay node is selected based on instantaneous and partial knowledge of the channel. In contrast withExpand

Max-min relay selection for legacy amplify-and-forward systems with interference
In this paper, an amplify-and-forward (AF) cooperative strategy for interference limited networks is considered. In contrast to previously reported work, where the effect of interference is ignored,Expand

Iterative Source-Channel Decoding With Markov Random Field Source Models
We propose a joint source-channel decoding approach for multidimensional correlated source signals. A Markov random field (MRF) source model is used which exemplarily considers the residual spatialExpand

Optimization of the index assignments for multiple description vector quantizers
The optimization criterion and a practically feasible new algorithm is stated for the optimization of the index assignments of a multiple-description unconstrained vector quantizer with an arbitraryExpand

Turbo cross decoding of multiple descriptions
The transmission of multimedia data over best-effort packet networks has motivated a strong research effort in the area of multiple description coding. While most contributions concentrate on theExpand

On the Minimax Risk of Dictionary Learning
We consider the problem of learning a dictionary matrix from a number of observed signals, which are assumed to be generated via a linear model with a common underlying dictionary. In particular, weExpand
