Massive MIMO and Base Station Cooperation are attracting much of the attention for the evolution of cellular networks. But, the performance evaluation of large cellular networks that implement such schemes becomes quite complicated. Thus, insights were mostly gained through the study of very simplified network models or through simulations. We present another approach, where we model the network node locations as random. Combining tools from stochastic geometry analysis and large matrix analysis, we are able to derive a simple expression for the network performance. This expression gives a simple characterization of the effect of all main network parameters (e.g., mobile density, base station density, number of antennas per base, number of cooperating bases and more). This expression is also verified by Monte Carlo simulations which indicate that it is useful for even a moderate number of antennas.
Itsik Bergel received the B.Sc. in electrical engineering and the B.Sc. in physics from Ben Gurion University, Beer-Sheva, Israel, in 1993 and 1994, respectively, and the M.Sc. and Ph.D. in electrical engineering from the University of Tel Aviv, Tel-Aviv, Israel, in 2000 and 2005 respectively. From 2001 to 2003, he was a Senior Researcher at INTEL Communications Research Lab. In 2005, he was a Postdoctoral researcher at the Dipartimento di Elettronica of Politecnico di Torino, Italy, working on the capacity of non-coherent channels. In 2004 he received the Yitzhak and Chaya Weinstein study award. He is a faculty member in the faculty of engineering, Bar-Ilan University, Ramat-Gan, Israel.
His main research interests include multichannel interference mitigation in wireline and wireless communications, cooperative transmission in cellular networks and cross layer optimization of random ad-hoc networks.
