Abstract

The most salient feature differentiating millimeter-wave communication systems from their predecessors will be the steerable pencilbeam antennas at the transceivers. As opposed to conventional widebeam antennas, only a few multipath components will be admitted into the pencilbeam. Although each component has a unique Doppler frequency shift, the combination of shifts across the components admitted will give rise to a Doppler spread. How wide that spread is uncertain because, to our knowledge, there are no such measurement results for millimeter- wave systems in open literature to date. To fill this void, we have designed an 83.5 GHz channel sounder that can measure the shift of multipath components in a mobile environment with super-resolution. By synthesizing the shifts through a simulated antenna with variable beamwidth, we can develop a parameterized model for the spread.
