This paper presents measured statistical distributions of incident waves to a mobile antenna in urban microcellular and indoor environments at 2.15 GHz. The power spectra of azimuth angle, elevation angle, and Doppler frequency are presented for horizontally and vertically polarized waves separately. The measurement campaign has been performed using a spherical dual-polarized antenna array and ...
