Expresiones cerradas de capacidad de sistemas MIMO 2X2 en canales arbitrarios

Abstract

Recent works have shown the potential performance MIMO systems based on dual-polarized antennas at transmitter and receiver. These works assume Rayleigh or Ricean channel models. In this paper we provide closed-form expressions of the ergodic capacity for arbitrary channels, being the Rayleigh and Ricean two particular cases. These expressions are function of the specific physical characteristics of the propagation environment and antennas, therefore they directly connect the ergodic capacity with the physical characteristics of the MIMO channel.
