DRM+ is a digital audio broadcast mode based on the DRM standard, primarily for use in the WFMWideband Frequency Modulation broadcast spectrum. It uses COFDMCoded Orthogonal Frequency-Division Multiplexing (Coded Orthogonal Frequency Division Multiplexing) with QAMQuadrature Amplitude Modulation (Quadrature Amplitude Modulation).
DRM+ differs from medium wave and HFHigh Frequency (3-30 MHz) DRM in that a 100 kHzKiloHertz (kHz) 10^3 Hz channel is used for transmission of the digital audio and data, as well as using robustness mode 'E' to guard against fading.
Frequencies[edit]
DRM+ is designed to operate in the VHFVery High Frequency (30-300 MHz) Broadcast Bands:
- Band I 47-60 MHzMegaHertz (MHz) 10^6 Hz
- Band II 87.5-108 MHzMegaHertz (MHz) 10^6 Hz
- Band III 174-230 MHzMegaHertz (MHz) 10^6 Hz
Decoding Software[edit]
Video Examples[edit]
- First realtime DRM+ transmission in Kaiserslautern
- DRM+ reception and FM reception in Edinburgh, March 2011
- Live DRM+ reception with RTL2832U stick
