Field Tests and Comparison of the Channel Properties for the DRM+ System in the VHF-Bands II (87.5 MHz-108.0 MHz) and III (174-230 MHz)
This paper presents a comparison of the channel properties for the DRM+ (Digital Radio Mondiale, Mode E) radio system in the frequency Bands II and III for mobile reception. The impact of different transmitting frequencies and receiver velocities is analyzed by simulations of the system performance with different channel profiles. A closer view is taken on the upper bounds of receiver velocities as this is the main problem for proper reception at higher frequencies. Additionally, measurements of the DRM+ system in the VHF- Bands II and III are presented to analyze and compare the performance in the real-world.
