System level abstraction and evaluation of non-orthogonal multiple access transmissions

The increasing demand for higher data rates and lower transmission latency requires new transmission techniques to be considered for future wireless networks. Non-orthogonal multiple access (NOMA) techniques promise higher data rates, lower latency and massive user deployments. To analyze the effects of NOMA techniques in networks, a system level abstraction is necessary to perform system level simulations with low complexity. This work introduces an efficient system level abstraction for power domain NOMA and provides an analysis of the effects of the deployment of NOMA techniques in wireless networks.6

Flexible multi-node simulation of cellular mobile communications: the Vienna 5G System Level Simulator

Abstract The investigation and prediction of new trends and technologies for mobile cellular networks is of utmost importance for researchers and network providers to quickly identify promising developments. With the verge of the fifth generation of mobile communications (5G), networks become more and more heterogeneous and dynamic while the amount of active users within a cell keeps ever increasing. Therefore, the search for more efficient network layouts and configurations attracts massive attention while on the other hand becomes more and more complex. In this contribution, we present the Vienna 5G system level simulator, which allows to perform numerical performance evaluation of large-scale multi-tier networks, with numerous types of network nodes. The simulator is based on Matlab and is implemented in a modular fashion, to conveniently investigate arbitrary network and parameter constellations, which can be enhanced effortlessly. We first discuss the distinguishing aspects of our simulator platform, describe its structure, and then showcase its functionality by demonstrating the key aspects in more detail
