Radio direction finding applied to DVB-T network for vehicular mobile reception

To improve the quality of the mobile reception of DVB-T (Digital Video Broadcasting - Terrestrial) signal, the knowledge of the propagation channel characteristics is necessary. In this aim, this paper presents sounding methods and results for the estimation of Direction of Arrival (DoA) of DVB-T signals in mobile receiving configuration. The mobile passive sounder is presented, including post-processing and radio direction finding tools. Then, results in different kinds of environment (rural area, motorway, low density and high density town centres) are given and discussed.
