Power Allocation Based on SEP Minimization in Two-Hop Decode-and-Forward Relay Networks
—The problem of optimal power allocation among the relays in a two-hop decode-and-forward cooperative relay network with independent Rayleigh fading channels is considered. It is...

Optimal relay functionality for SNR maximization in memoryless relay networks
We explore the SNR-optimal relay functionality in a memoryless relay network, i.e. a network where, during each channel use, the signal transmitted by a relay depends only on the ...
