ABSTRACT
In this paper, we present a modified sum-of-sinusoids (SOS) based simulator for a two-dimensional (2-D) non-isotropic scattering channel. With a new parameter computation method called equal probability area (MEPA), the proposed model can be applied on arbitrary 2-D scattering environments and also can be generalized to multi-path channels with respect to the principle of set partitioning. Simulation results verify that the first and second order statistics of the output channels approximate the reference model with a high precision and when the theoretical results are unknown, it can be used as a reference for unusual distributions.
