In this work we consider multiple antenna systems in which a large number of antennas occupy a given physical volume and we investigate the behavior of the capacity when increasing the number of antennas. In this regime the assumptions of the standard multiple antenna models become questionable. We introduce several new channel models that better fit this(More)
— In this paper we study the downlink spectral efficiency of a wireless network using Orthogonal Frequency Division Multiple Access (OFDMA), Multiple Input Multiple Output (MIMO) antenna systems and Opportunistic Scheduling (OS) techniques. The main purpose of the study is to understand how these techniques interact and influence the spectral efficiency of(More)
Digital communications using multiple antenna wireless links figure prominently on the list of hot technologies that may have a chance to resolve the bottlenecks of traffic capacity in the forthcoming high-speed broadband wireless internet access networks (WiMax, LTE and beyond). In order to show the huge potential of using multiple antenna systems within(More)
