Statistical Simulation Modeling of 3-D HAP-MIMO Channels

High altitude platforms (HAPs) have been designated as an alternative wireless infrastructure for facilitating next generation high-speed mobile communications services. This paper deals with the design and performance evaluation of a three-dimensional (3-D) sum-of-sinusoids statistical simulation model for HAP multiple-input–multiple-output Ricean fading channels. The performance of the simulation model is investigated with respect to the temporal and spatial correlation functions. The results indicate that the simulation model accurately and efficiently approximates the statistical properties of a recently proposed nonrealizable reference model.
