Two-dimensional shadow fading modeling on system level

In this paper, we propose a novel complete two-dimensional shadow fading modeling on system level characterized by both spatial auto-correlation and site-to-site cross-correlation. Numerical results confirm that the proposed algorithm based on two-dimensional filter to generate shadowing auto-correlation is more approaching theoretical results comparing with the previous method, and the empirical cross-correlation coefficient is embedded well in our proposed model. Additionally, the linear interpolation scheme of the proposed model significantly reduces the computational complexity on system level simulation.
