Abstract:

In this paper, firstly presented a geometrically based statistical channel model with scatterers that are with inverted parabolic spatial distribution around mobile station (MS) within a circle wherein the base station (BS) and MS are included. This paper presented a technique to simply derive PDFs of AOA, TOA and Doppler spectra to characterize the outdoor macrocell and microcell wireless environments by employing various distances between BS and MS, or different size of circular region. Employing this channel model, we analyze the impacts of a directional antenna with the main-lobe width at BS on the fading and the Doppler spectra.

Key words:
