Space - time dynamic channel model for broadband fixed wireless access

Broadband fixed wireless access is a point-to-multipoint technology for providing broadband services. These systems need a space-time channel model which accounts for the spatial and temporal variation of rain attenuation for simulating fading mitigation techniques such as adaptive coding and modulation, and other capacity enhancing techniques. In this paper we study the space-time correlation of rain attenuation, and propose a simulation model for generating correlated rain attenuation time series base on the generalised Maseng-Bakken model. In addition, the parameter beta controlling rain attenuation dynamics in the Maseng-Bakken model have been extracted from measurements and shows variations with location within a single rain event.
