Resolving the angular profile of 60 GHz wireless channels by delay-Doppler measurements

Previous channel measurement campaigns in millimetre wave bands were mostly focussing on time invariant channels of static environments. Highly directive antennas were swept in azimuth and elevation angle to extract the angular profile of the double-directional radio channel. This angular profile is...

Summary:Previous channel measurement campaigns in millimetre wave bands were mostly focussing on time invariant channels of static environments. Highly directive antennas were swept in azimuth and elevation angle to extract the angular profile of the double-directional radio channel. This angular profile is also visual in the Doppler domain. Therefore, contrary to common Doppler modelling, close scattering objects have to be taken into account. In this paper, a methodology for repeatable estimation of the angular profile through delay-Doppler measurements is proposed. Repeat-able measurements of the static scenario allow for 1) optimization of the probing signals to reduce the geometrical effects and 2) disambiguation of the angular estimates through different measurement positions.
