A radio receiver is disclosed. The radio receiver includes an analog tuner and a baseband processor to provide radio functions. The baseband processor is coupled to the analog tuner. The radio receiver further includes a memory, a controller coupled to the analog tuner, the baseband processor and the memory. The controller is configured to perform an operation, the operation includes causing the analog tuner to analyze a selected FM frequency to determine if the selected FM frequency is associated with a digital radio mondiale (DRM) plus station by first coarsely determine if the selected FM frequency may be associated with a DRM plus station and if coarse determination fails, marking the FM frequency as not being associated with a DRM plus station, wherein if the coarse determination is successful, retrying a selected number of times to continue to determine if the selected FM frequency is associated with a DRM plus station.

Detection for digital radio mondiale plus in hybrid broadcasting mode

A radio receiver is disclosed. The radio receiver includes an analog tuner and a baseband processor to provide radio functions. The baseband processor is coupled to the analog tuner. The radio receiver further includes a memory and a controller coupled to the analog tuner, the baseband processor and the memory. The controller is configured to perform an operation and the operation includes causing the analog tuner to scan a spectral band to identify radio stations and based on a signal matrix obtained from scanning a station in the spectral band tentatively determining if the station represents a digital radio mondiale (DRM) station and if so, storing the station in a list of possible DRM stations in the memory.
