Abstract:
This paper presents the first DRM+ (Digital Radio Mondiale, Mode E) Single Frequency Network (SFN) in the air. A field trial has been conducted to evaluate the performance in different environments. Due to it’s relatively small bandwidth, flat fading in the overlapping area can become a problem. Different solutions to overcome this problem are evaluated in this paper. Adding different delays to transmitters side-by-side is a solution to overcome the flat fading. In the field trial the error rates in the overlapping area in a two TX setup with delay were significantly smaller than without delay, the probability of deep fades was becoming smaller. This paper provides parameters for applying a Single Frequency Network with DRM+.
