Statistical channel model based on α-stable random processes and application to the 60 GHz ultra wide band channel

Abstract

In this paper, we introduce a statistical model of the ultra wide band channel impulse response at 60 GHz. The novelty of our model is to consider the transfer function as an α-stable random process. It leads to a characterization of the channel by a deterministic measure that can be estimated from observed transfer functions. We present the theoretical framework of our proposed solution and the necessary tools to estimate the characteristic measure and generate the impulse responses. Simulations based on 2 GHz wide channel measurements in the 60 GHz band show the validity of our model.
