Abstract

This letter presents the results of field trials conducted in Brazil to evaluate the performance of digital broadcasting systems. Analog FM and digital HD radio signals broadcasting the same content were simultaneously transmitted in the urban and suburban areas of the city of Belo Horizonte in Brazil. A mobile unit recorded the received signal intensity and reception quality along radial routes of up to 24 km from the transmitter, thereby enabling the comparative assessment of the systems performance and the evaluation of the propagation loss.
