Wideband Off-Body Channel Characteristics with Dynamic User
This paper presents the preliminary results of a dynamic off-body channel characterisation study, based on wide-band measurements at 5.8 GHz in an indoor environment. The Channel Impulse Response (CIR) was measured for a scenario with the user approaching and departing from the off-body antenna. A CIR deconvolution procedure was performed jointly in two polarisations, and the received signal power, Cross-Polarisation Discrimination (XPD), delay mean and standard deviation were calculated based on the estimated path delays and amplitudes. The statistical analysis is performed, and the obtained results show large variations of the CIR parameters. The XPD is observed to vary up to 21.3 dB.
