Propagation Channel Characteristics for Peer-to-Peer Multiple Antenna Systems at 300 MHz

This paper presents results from the first double-directional measurements of the Multiple-Input Multiple-Output (MIMO) peer-to-peer radio channel in the 300 MHz frequency range. The measurements were performed with vertically polarized circular antenna arrays mounted on cars driving along a route in a semi rural and sub-urban environment. We evaluate the measurements with a high resolution algorithm, thus obtaining a wideband, double-directional characterization of the propagation channel. The delay and directional spread, as well as the small-scale fading statistics are analyzed along the measurement routes and major scatters are identified. The measurements, performed with low antenna heights, show high angular spreads, caused by reflections from trees and buildings and by diffractions over terrain irregularities. We further observe multiple clustes in both the delay and angular domains. The large spreads in these domains indicate a high degree of available diversity, and rich m...
