Modelling of indoor propagation for the band of frequencies ranging from 20 to 60 GHz

This article proposes a model which seeks first to describe the signal S(t) received when a receiver is moved within a building while a sinusoidal wave at a frequency amounting to more than 20 GHz is transmitted. The hypotheses on which it rests are quite general so that it is useful in other contexts. They depend upon experimental results. The model is one with Rayleigh distribution containing two rays. It has the feature of binding explicitly the variations in phase of S(t) to variations in amplitude, and can facilitate the simulation of wave propagation in the channel being modelled. This characteristic is desirable so that it is in order to employ the proposed model when simultaneous reception of a large number of signals is to be simulated
