Opportunistic relays selection for successive relaying with inter-relay interference
2015 IEEE 12th Malaysia International Conference on Communications (MICC), 2015In the presence of inter-relay interference, the capacity performance of successive relaying can be severely degraded. Existing literature on successive relaying does not consider the channel quality of the inter-relay channel in maximising the capacity performance.

PHILOSOPHICALLY the electric power system exists to serve certain human needs and it must serve them better and more economically than they could be served by other methods or it would not be able to continue to exist or to grow. The rendering of service of the required degree of excellence, within economic limitations, is not an inherent attribute of ...

Blackouts and relaying considerations - Relaying philosophies and the future of relay systems
IEEE Power and Energy Magazine, 2006This paper addresses the broad question of relaying philosophies, modes of operation of relays under abnormal system conditions, the categories of their failure modes, and advances made possible by modern technology in computer relays, adaptive relaying, and the use of wide-area measurements for improved protection and the ability to mitigate wide-area

Piecewise-and-Forward Relaying in Wireless Relay Networks
IEEE Signal Processing Letters, 2011In this letter, we propose a piecewise-and-forward (PF) relaying protocol for wireless relay networks. In PF, the received signal at each relay is compared to an adaptive threshold. If the amplitude of the received signal is above the threshold, the relay will decode the signal, otherwise, the relay will forward the received signal after linear ...

The Multiple-Relay Channel with Estimate-and-Forward Relaying
2007 IEEE International Symposium on Information Theory, 2007In this paper we consider the multiple-relay channel. For this scenario there are two well known results: the decode-and- forward (DAF) result of [Xie and Kumar, 2005] and the estimate-and forward (EAF) result of [Kramer et al., 2005]. However, the EAF result does not lend itself to numerical evaluation due to the large number of parameters to be ...

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}).

A Novel Relay Selection Algorithm for Relaying Networks
2009 IEEE 70th Vehicular Technology Conference Fall, 2009Cooperative diversity has been recently proposed as a way to form virtual antenna arrays that provide dramatic gains in slow fading wireless environments. In a multiple-relay network, the opportunistic relay selection scheme has been shown to outperform any other strategy that involves the conventional all-participate scheme.

On the selection of relays' positions in diamond relay networks
Proceedings of the 6th International Wireless Communications and Mobile Computing Conference, 2010Diamond relay network is a kind of efficient cooperative network, in which the source user selects two neighbors as relays and cooperates with both of them. In our previous work, we have studied its transmission rates for different coding and relaying schemes and proved that the performance of SRP scheme (Spatial Reuse Pattern) is better than others ...

On the Position Selection of Relays in Diamond Relay Networks
IEEE Transactions on Communications, 2011The diamond relay network is an efficient cooperative networking configuration in which the source node cooperates with two selected neighbors. For such networks, we investigate the impact of the relay positioning on the performance. In particular, considering an opportunistic protocol based on the use of relaying buffers, we provide sets of ...
