Sentence examples for based on relay selection from inspiring English sources

Some protocols based on relay selection in cognitive radio were studied.

A key contribution of this article is a low complexity inter-relay power allocation method which is based on relay selection.

For the multiple relay case, it is shown that the resource partitioning based on relay selection is enough to find the best relaying configuration.

Since it is difficult to obtain a closed form solution for the problem, we propose a low-complexity technique based on relay selection using uniform gain allocation, which has near-optimal performance in terms of capacity.

Spectrum sharing protocols based on amplify-and-forward relaying in Rayleigh and Nakagami-m fading were studied in [27, 28], and the outage performances of the protocols based on relay selection in Rayleigh and Nakagami-m fading were studied in [29, 30], respectively.

We analyze the existing trade-offs in terms of system performance versus fairness of a cooperative system based on opportunistic relay selection (ORS) and with outdated channel state information (CSI).

A threshold based relay selection scheme is considered, in which the reliable relays are determined by comparing source-relay SNR to a threshold, and one of the reliable relays is selected by the destination based on relay-destination SNR.

In this regard, this article focuses on relay selection based on partial channel knowledge only across the source and relay links.

We divide our communications into four phases as follows.In phase 1 of Figure 2a, the source node broadcasts its modulated signal to the selected relay (based on the optimum relay selection technique described in section 4.2) and the destination nodes through wireless channels.

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.
