Relaying selection based multiple access relay channel
2016 24th Signal Processing and Communication Application Conference (SIU), 2016Relay selection in case of fast cascade Rayleigh fading channels has been examined in multiple access relay channel structure which is one of the high spectral efficiency network coding applications. Error performance analysis of MARC system has been made for noncoherent binary frequency shift keying (BFSK) and it has been shown that the proposed ...

Incremental Relaying with Partial Relay Selection
IEICE Transactions on Communications, 2010We propose an incremental relaying protocol in conjunction with partial relay selection with the aim of making efficient use of the degrees of freedom of the channels as well as improving the performance of dual hop relaying with partial relay selection (DRPRS).

Relay selection in bidirectional relay communication
2007 IEEE 8th Workshop on Signal Processing Advances in Wireless Communications, 2007We consider the problem of relay selection in a scenario with N relay nodes. A half-duplex relay node enables bidrectional communication between two nodes with a spectral efficient two phase protocol. In the first phase, both nodes transmit a message to a relay node, which decodes the messages and broadcasts a composition in the succeeding phase.

QoS Provisioning Relay Selection in Random Relay Networks
IEEE Transactions on Vehicular Technology, 2011In this paper, we propose an analytical framework for determining the outage probability of random and best relay selection schemes given a Poisson field of relay nodes and the presence of path loss and fading. For relay selection, relays geographically close to the source and destination are preferred to others.

Adaptive relay selection for hybrid relay systems
2010 The 2nd International Conference on Computer and Automation Engineering (ICCAE), 2010Hybrid relay systems using Amplify-and-Forward protocol (AF) and Decode-and-Forward protocol (DF) together are introduced in cooperative networks. For hybrid systems, we propose adaptive relay selection scheme to maximize the overall received Signal to Noise Ratio (SNR) at the destination.

Hybrid relay selection in heterogenous relay networks
2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers, 2010In this paper heterogenous networks are envisioned where multiple amplify-forward (AF) and decode-forward (DF) relays coexist. Consider a representative case with one source, one destination, and multiple relays, where at each point in time a subset (e.g. two) of the relays can be active simultaneously.

Selective Relay-Activation for Conditional DF Relaying
IEEE Transactions on Communications, 2014This paper considers a conditional decode-and-forward (DF) based cooperative system where a source (S) with multiple (M) antennas transmits information to a single-antenna destination (D) with the help of multiple (L ≤ M-1) single-antenna relays ({R_i}).

Relay selection in multiple clustered relay networks
2015 Wireless Telecommunications Symposium (WTS), 2015We consider the downlink of a realistic cellular network composed of multiple clusters, each of which includes multiple relays and a destination terminal. In this scenario, the interference among the clusters is a critical issue, affecting the end-to-end performance of the system significantly.
