Opportunistic half-duplex/full-duplex relaying mode selection criterion in cognitive relay networks
In this paper, adaptive transmission in a cognitive relay network where a secondary transmitter acts as cooperative relay for a primary transmitter while in return gets the opportunity to send its own data is considered. An opportunistic half-duplex (HD)/full-duplex (FD) relaying mode selection criterion which can utilize the advantages of both HD and FD is proposed. The key idea is that the co...
متن کاملSimple relaying strategies for half-duplex networks
We consider the diamond network where a source communicates with the destination through N non-interfering half-duplex relays. Using simple outer bounds on the capacity of the network, we show that simple relaying strategies having exactly two states and avoiding broadcast and multiple access communication can still achieve a significant constant fraction of the capacity of the 2 relay network,...
متن کاملFull-Duplex Relay Selection in Cognitive Underlay Networks
In this work, we analyze the performance of fullduplex relay selection (FDRS) in spectrum-sharing networks. Contrary to half-duplex relaying, full-duplex relaying (FDR) enables simultaneous listening/forwarding at the secondary relay(s), thereby allowing for a higher spectral efficiency. However, since the source and relay simultaneously transmit in FDR, their superimposed signal at the primary...
متن کاملA Study of Half-Duplex Asymmetric Two-Way Decode-and-Forward Relaying Using Relay Selection
This paper examines the information theoretic metric of outage probability for a decode-and-forward (DF) based asymmetric two-way relay transmission (i.e. the two source terminals have different target rates). We first characterize the achievable rate region of a conventional three-node network. After that the conventional three-node scenario is analyzed in terms of outage probability and the c...
متن کاملAchievable Rates Of Half-Duplex Relay Networks
This paper discusses two coding approaches for a network of half-duplex relay terminals and presents achievable rates for the discrete memoryless relay channel. Both proposals gain on an implicit (in case of compress-and-forward) or explicit (in case of decode-and-forward) inter-relay cooperation.
