This article, which was posted to Automotive DesignLine on 11/7/08, describes how to use software-defined radio (SDR) techniques to receive a number of different standard signals, including:
- Digital Radio Mondiale (DRM)
- DRM+
- Digital Audio Broadcasting (DAB)
- DAB+
- Terrestrial Digital Multimedia Broadcasting (T-DMB) digital TV
- HD-radio AM
- HD-radio FM
It looks to me like these techniques could also be used in amateur radio. At the very least, the article is an interesting read.
