Wireless Single Cellular Coverage Boundary Models

To satisfy the requirement of high wireless transmission rate from user terminals, the multi-cell cooperative communication is an important solution for cellular networks. The selection of cooperative cells is usually depended on every wireless single cellular coverage boundary in cellular networks. In this paper, we analyze the characteristics of wireless single cellular coverage boundary based on real measured data. Moreover, the alpha-stable processes are first proposed to model the wireless single cellular coverage boundary. Simulation results indicate that probability density functions of wireless single cellular coverage boundary can be fitted by alpha-stable processes with 95% confidence interval based on the real measured data. This result provides a basis for cooperative communications considering the anisotropic fading characteristic of wireless signal propagation in wireless single cellular coverage region.
