In this work, we consider the multiple antenna systems in which a large number of antennas occupy a given physical volume, and 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(More)
Acknowledgments If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties. 1 Einer hat immer Unrecht: aber mit Zweien beginnt die Wahrheit. Einer kann sich nicht beweisen: aber Zweie kann man bereits nicht widerlegen. It was a great pleasure to be the pupil and student of Bixio(More)
This paper presents the implementation of a multiple antenna communication system using low-density parity-check (LDPC) codes on the software-defined radio (SDR) platform developed at EPFL's Mobile Communications Laboratory. After briefly presenting the general structure and the main capabilities of our SR platform, we describe the methods and algorithms(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)
