C-N. Chuah - Multi-Antenna Arrays

Multiple-Antenna Array Systems

I worked on this topic for my M.S. studies at U. C. Berkeley, and my advisors are Prof. Joseph Kahn and Prof. David Tse.

Abstract
This work is inspired by the large capacity increase that may be achieved by using multi-element antenna arrays (MEA) at both transmitting and receiving sites. Previous studies have shown that a wireless system using n transmitting and n receiving antennas canachieve a cpacity n times higher than a single-antenna system in an independent Rayleigh fading environment. In this work, we explore the capacities of MEAs in a more realistic propagation environment simulated via the WiSE (Wireless System Engineering) ray-tracing tool. We impose an average power constraint and collect statistics of the capacity with optimal power allocation, C_wf, and the mutual information with an equal power allocation, I_eq. In addition, we present expressions for the asymptotic growth rates C_wf/n and I_eq/n as n approaches infinity for two cases: (a) independent fadings and (b) correlated fadings at different antennas.
