A practical forwarding scheme for wireless relay channels based on the quantization of log-likelihood ratios
This paper considers a wireless relay network with one source, one relay, and one destination. We propose a low-complexity quantize-and-forward (QF) scheme in which the relay calc...

Packet level performance analysis in wireless user-relaying networks
In this paper, the impact of user relaying on the behavior of a relay node, which acts as the source node at the same time, is analyzed in a wireless relay network at the packet le...
