Abstract :
In this paper, an approximation to the mathematical evaluation of the spectral and energy efficiency of multi-antenna downlink cellular networks is introduced. The locations of the Base Stations (BSs) are modeled as points of a Poisson Point Process (PPP) and stochastic geometry is used for system-level performance assessment. The approximation is applicable to spatial multiplexing Multiple-Input-Multiple-Output (MIMO) systems having an arbitrary number of antennas at the transmitter (Nt) and at the receiver (Nr). A Rayleigh fading channel model is assumed. The accuracy of the proposed approximation is substantiated with the aid of Monte Carlo simulations.
