TLDR
In this article, a cooperative network with multiple source-destination pairs and one EH relay is considered and the outage probability experienced by users in this network is characterized by taking the spatial randomness of user locations into consideration.Abstract:
This letter considers a cooperative network with multiple source-destination pairs and one energy harvesting relay. The outage probability experienced by users in this network is characterized by taking the spatial randomness of user locations into consideration. In addition, the cooperation among users is modeled as a canonical coalitional game and the grand coalition is shown to be stable in the addressed scenario. Simulation results are provided to demonstrate the accuracy of the developed analytical results.read more

On the Performance of Non-Orthogonal Multiple Access in 5G Systems with Randomly Deployed Users
TL;DR: In this letter, the performance of non-orthogonal multiple access (NOMA) is investigated in a cellular downlink scenario with randomly deployed users and developed analytical results show that NOMA can achieve superior performance in terms of ergodic sum rates; however, the outage performance of N OMA depends critically on the choices of the users' targeted data rates and allocated power.
