An Impulse Response Model for the 60 Ghz Channel Based on Spectral Techniques of a-stable Processes

Abstract

Abstract-In order to make realistic simulations of the radio propagation mechanism in ultra-wide band channels, an appropriate model is usually needed. In this paper we give a new technique of modeling the impulse response of the 60 Ghz channel. This new approach is based on the spectral analysis of α-stable processes. Our new model present many advantages : firstly, the channel is characterized only by a one deterministic function(spectral density) in the place of four parameters. Secondly, the estimations procedures deals directly with the measured transfer functions this avoid loosing informations in data pretreatments. Finally, an estimation of the spectral measure permit to directly generate the impulse response.

A successful VISION: Video-oriented UWB based intelligent ubiquitous sensing

“…Some research activities in 60 GHz environment have been carried out [5] [6], however a comprehensive channel model that enables tractable analysis is not yet available. In this project, extensive channel measurements on the 60 GHz region will be performed using an UWB channel sounder with a resolution of 0.4 ns, based on pulse compression techniques using pseudo-noise (PN) sequences.…”

Analyzing 60 GHz radio links for indoor communications

“…Therefore, we first discuss a ray-based model for characterizing the 60 GHz radio propagation towards the receiver. Comparatively, the generally used models such as lognormal path loss model, kray model [19] and impulse response model [20] focus on the path loss phenomena on the average, whereas our ray-based model is able to analyze the instantaneous shadowing effect that blocks certain propagation paths of the 60 GHz radio wave due to the presence of people around the transceivers.…”
