UHF Wideband Mobile Channel Measurements and Characterization using ATSC Signals with Diversity Antennas

Recently, there have been increasing interests to characterize the UHF wideband mobile reception. In the literature, there are several studies on UHF mobile reception for cellular phone systems, however, most of them addresses narrowband services. This paper presents propagation measurement results on UHF TV band using the ATSC Digital Television as a sounding signal to study the characteristics of wideband Digital Television (DTV) channel under mobile reception conditions. The analysis of the measurement data presented in this paper shows that channel characteristics depend strongly on surrounding environments and receiver’s parameters, such as the vehicle speed relative to the transmitter-receiver axis.
