Sentence examples for various relay selection from inspiring English sources

Future study may consider the use of alternate forwarding protocols (such as amplify-and-forward or equalize-and-forward) as well as the overhead tradeoff of the various relay selection methods.

We derive the DMT for several relaying strategies: best relay selection, random relay selection, and the case when all decoding relays participate.

These strategies are: selective AF, selective DF, and partial relay selection AF relaying.

In this part, all the relay nodes are selected by our cooperative relay selection scheme.

Various decode-and-forward protocols have been proposed based on selective relaying, distributed space-time coding, and relay selection and have been shown to achieve full diversity [1 5].

Besides, various advanced techniques have been employed to enhance the physical layer security of CRNs, such as multiple antenna diversity in [7 10], relay selection in [11 14], artificial noise in [13], and secrecy beamforming/precoding in [6].

Then a joint optimization, in terms of power allocation and relay selection, is employed to guarantee a robust performance for relay selection based on partial relay link.

The mechanism of cooperative relay selection is very essential for the design of heterogeneous wireless relay networks.

We prove rigorously that such an approach leads to a relay selection algorithm where the relay with the strongest channel coefficient to the master transceiver participates in relaying and the remaining relays are shut off.

In this paper, based on the self-similar nature of network traffic in heterogeneous wireless cooperative relay network, we propose a new relay selection mechanism called conditional relay selection which can effectively decrease the system outage probability.

A joint power allocation and relay selection scheme is designed to achieve the minimum transmit power.
