%T 4D Arrays for New Generation MIMO Applications %L elediasc12634 %X In this report, an innovative application of 4-D arrays is proposed and assessed. The possibility to simultaneously receive multiple signals impinging on the antenna from different directions such to increase the wireless system throughput by means of a proper definition of the pulse sequence controlling the on-off behavior of the RF switches is investigated. %D 2014 %A E.
