The fifth-generation cellular networks aim to provide uniform and very high throughput. Massive MIMO is widely seen as the most promising 5G radio technology as it promises very high throughput to many users while also guaranteeing fairness, thanks to the channel hardening effect limiting the small-scale fading. A key question though is to what extent this achieved throughput is homogeneous among...
Nonlinear power amplifiers distort the transmitted signal and out-of-band (OOB) radiation becomes a source of interference for users operating in adjacent channels. This paper studies the effect of Massive Multiple Input Multiple Output (MIMO) system on the OOB interference. Massive MIMO relies on channel based precoding which ensures the signal is added constructively at the receiver user equipment...
In this paper we introduce an air-to-ground channel model extension for a multi-antenna system. The performance of an aeronautical communication system is strongly influenced by the presence of scatterers and by the three-dimensional (3-D) configuration of transmitter and receiver such as location and velocity. Combined statistical and geometrical models were used to offer a time-space description...
