Better than Rician: modelling millimetre wave channels as two-wave with diffuse power

Physical optics modelling of millimetre-wave personnel scanners

We describe the physical-optics modelling of a millimetre-wave imaging system intended to enable automated detection of threats hidden under clothes. This paper outlines the theoretical basis of the formation of millimetre-wave images and provides the model of the simulated imaging system. Results of simulated images are presented and the validation with real ones is carried out. Finally, we pr...

Millimetre Wave with Rotational Orbital Angular Momentum

Orbital angular momentum (OAM) has been widely studied in fibre and short-range communications. The implementation of millimetre waves with OAM is expected to increase the communication capacity. Most experiments demonstrate the distinction of OAM modes by receiving all of the energy in the surface vertical to the radiation axis in space. However, the reception of OAM is difficult in free space...

Joint Parameter Estimation for the Two-Wave with Diffuse Power Fading Model

Wireless sensor networks deployed within metallic cavities are known to suffer from a very severe fading, even in strong line-of-sight propagation conditions. This behavior is well-captured by the Two-Wave with Diffuse Power (TWDP) fading distribution, which shows great fit to field measurements in such scenarios. In this paper, we address the joint estimation of the parameters K and Δ that cha...
