Multiple-input-multiple-output (MIMO) wireless channel models are often too simplistic to accurately model wireless propagation effects or too complex and/or site specific to be used for analytical purposes. In this paper, we develop a double-directional MIMO channel model that accounts for important propagation effects like scattering, clustering, and channel depolarization and antenna effects like...
A measurement campaign to investigate the polarisation behaviour of on-body communication channels using a dual polarised antenna is reported. The antenna is a combination of a monopole and loop antenna, which yields the required vertical and horizontal polarization respectively in the XY plane. Measurements were done using this antenna on the body in indoor environment. The collected data has been...
The implementation of multiband OFDM ultra wideband (MB-OFDM UWB) technology into wireless devices aims to enhance transmission capacities for low-range wireless communication systems. Although OFDM transmission provides a certain robustness against multipath interference, miss-aligned antenna elements may largely impact on the resulting signal-to-noise (SNR) conditions thus limiting the UWB link...
This paper investigates the effective gain of antennas in indoor channels. A metric called instantaneous effective gain is proposed, and a multiple-cluster 3D channel model is used to facilitate the proposed antenna effective gain. In the multiple-cluster channel model, Laplacian and double exponential distribution are utilized to model azimuth and elevation signal power distribution respectively,...
