Abstract :
This paper discusses radiation pattern selection in multiple-input multiple-output (MIMO) wireless systems. Each receive antenna can be reconfigured to P distinct radiation patterns. We select radiation patterns in order to maximize instantaneous channel capacity. And we prove that for arbitrary correlation the maximum achievable diversity order of the pattern selection MIMO (PS-MIMO) system equals to the rank of the total correlation matrix of its full system so that the link reliability can be significantly improved. We propose a fast selection algorithm as the suboptimal solution for channel capacity maximization. For PS-MIMO systems over spatially correlated channels, we propose to use only a part of available radiation patterns based on the estimation of the correlation before performing the pattern search. Simulations are used to validate the theoretical results and illustrate the performances of proposed algorithms.
