Dynamic channel properties based on diffuse scattering from vehicles for high frequency bands in NLOS urban environments

Abstract

We describe dynamic channel properties based on diffuse scattering from vehicles for high frequency bands in a non-line-of-sight (NLOS) urban environment. We investigate the dominant paths based on the measured power delay angular profile in experiments using a 20-GHz band channel sounder. Based on the results, we clarify that arrival waves from buildings and diffuse scattering from vehicles represent dominant paths in NLOS urban environments. Also, we find that the fading of scattering paths from vehicles is approximately 26 dB in those paths between birth and death.
