Abstract:

A modified sum-of-sinusoids (SoS) channel model for two-dimensional (2D) non-isotropic scattering conditions is proposed. With the new parameter computation method, called equal probability areas (MEPA) of the angle of arrival (AoA), it can be applied on any single-path channel simulation with given distribution of AoA.It is also easy to use the principle of set partitioning to improve the performance or simulate multi-path channels. Analysis and simulation results demonstrate that the auto-correlation function, Doppler power spectrum and other second order statistics of the new model are close to the theory model, and better than other models.
