Abstract :
The delay cross-scattering function and the delay-Doppler scattering function of the mobile radio channel are derived assuming that the receiver moves randomly according to a Brownian motion and a stochastic motion which is developed based on experimental models describing unconstrained human arm movements. Estimates of these two functions obtained by simulating such movements in an outdoor microcellular environment are in good agreement with theoretical results
