Sentence examples for by the relay selection from inspiring English sources

The performance of network-coded cooperative networks is heavily determined by the relay selection scheme.

For example, channel state information and SNR are required by the relay selection approaches proposed in [11,12], respectively.

The proposed STBC-CQ-PNC scheme is introduced in Sect. 3 followed by the relay selection base on minimum residual interference power in Sect. 4.

However, it is worth noting that in LTE-A advanced location methods are available and can be used by the relay selection mechanism proposed in this article.

Also, we define as the SNR employed by the relay selection mechanism, which can differ from the actual SNR SNR but both of them have the same long-term average (further details can be found in Section 2.3).

By this means, the relay selection is designed with "one step looka-head" policy so that the energy efficiency performance can be achieved in a time horizon.

Step 2: Using the optimal number of messages/data blocks policy μ n given by (39), we calculate the relay selection policy to maximize the expected total throughput with piecewise linear value functions described above.

If conventional power allocation is used with the relay selection, the number of selected relays need to be broadcasted by the destination.

Nodes compete in the relay selection process by setting timers based on the channel state.

In other words, the standard deviation of the power consumption depends on the degree of fairness applied by the ORS-based schemes on the relay selection procedure, but for a given degree of fairness, it is only the outage probability that depends on the quality of the channel estimate but not the power consumption distribution.

In this approach, after the relay selection is realized by using Equation 28, the soft information is transmitted to the destination by amplifying (scaling) and forwarding the LLRs at the output of the decoder (decoder-LLR) [17] instead of making binary hard decisions.
