Abstract:
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 proļ¬les. 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. The theoretical work show that reception is possible up to receiver velocities of around 200 km/h in Band III in a worst case scenario. The measurements show comparable results for Band II and III.
