Performance analysis for adaptive MIMO SVD transmission in a cellular system

Abstract

In this paper we consider the performance of an adaptive MIMO SVD (singular value decomposition) transmission scheme operating in a cellular environment. In particular we consider the impact of inter-cell interference on the performance of an adaptive MIMO system. Inter-cell interference is always present in a cellular system. However, its value may be controlled by the type of cellular layout, i.e., the number of sectors and the frequency reuse pattern. In this paper we consider a number of cellular layouts and consider the impact of the resulting SINR on the constellation sizes that can be supported, the BER, etc. The primary metric used for our performance analysis is the error free transmission rate, and this is derived for the adaptive MIMO SVD system. For the cellular scenarios considered, we find that the effect of interference is considerable and the performance of the adaptive MIMO SVD scheme is only marginally better than that provided by conventional diversity methods
