Abstract:
Time-varying nature of mobile fading channels can affect the design of wireless systems in many different aspects. This paper investigates the dynamic behavior of intrinsic spatial links in multiple-input multiple-output (MIMO) transceivers based on Geometric mean decomposition (GMD). In particular, we suggest using a finite-state Markov chain (FSMC) to model the fluctuations of both eigenmodes geometric mean and capacity for MIMO-GMD schemes in Rayleigh fading channels. In order to compute the transition probabilities analytically, a number of related statistical distributions are developed and employed. Simulation results have illustrated that FSMC can provide accurate approximations.
