Sentence examples for multiple SUs share from inspiring English sources

Based on how multiple SUs share their detection results, cooperative PU detection can be classified into three categories [8]: centralized manner that all SUs forward the results to a fusion center (FC) [7, 9 11], distributed manner that SUs communicate with others directly [12], and relay-assisted manner that one or more SUs serve as relays to assist other SUs in forwarding the results [13, 14].

Meanwhile, using p D min * = 0.94 instead of 0.95 changes p from 0.833 to 0.714, which allows a bigger probabilistic capacity margin for multiple SUs to share available opportunities.

In the latter type of protocols, multiple SUs need to share their local sensing results.

A similar optimization with a more complete secondary co-channel transmission model is described in [14], in which each channel is shared by multiple SUs.

Within the scope of this article, it is therefore assumed that the base station under consideration is shared by multiple PUs and multiple SUs.

A game theoretic Cournot model is presented in [24], which considers the problem of spectrum sharing among a PU and multiple SUs.

This method is particularly useful in cooperative beamforming for mobile spectrum sharing scenarios where a PU and multiple SUs co-exist.

The aforementioned resource allocation methods share some common drawbacks which limit their applicabilities in cooperative spectrum sharing networks in cases where a PU and multiple SUs coexist.

To flexibly implement spectrum sharing between the PUs and the SUs and enhance the spectrum efficiency, a dynamic resource allocation (DRA) for multiple SUs is required.

Multiple SUs buy spectrums from multiple owners in [16].

Multiple PUs, multiple SUs, and multiple relays are considered in our model.
