Abstract
Abstract:
In this paper we have introduced an S-parameter based approach for computation of MIMO channel matrix where the
entire channel model is developed using half-wave dipoles. For the model under consideration, suitably terminated dipole
antennas represent scatterers with different scattering coefficients. We first validate our approach by comparing
results obtained by our method with the results already reported in literature for similar model evaluated using
different method. Using our proposed method, we determine the variation of capacity of a MIMO link as function of
separation of antennas in the mobile station for a macrocellular scenario where the scattering environment is
represented by a ring of scatterers surrounding the mobile station. We further extend our approach for modeling a dual
polarized MIMO system. Simulation results on capacity match with the expected results that further corroborate the
effectiveness of our approach.
