Development of Multi-Standard Digital Radio Chipset with Shared Logic and Memory

The digital transition of analog TV is rapidly taking place throughout the world. However, the digital transition of radio is progressing at a slower rate. Diverse standards are being considered for adoption and different countries have different frequencies allocated for digital radio. As a consequence, the progress in the development of digital radio receiver chipsets has been rather stagnant. In this paper, the design and implementation of a receiver chipset with integrated baseband and RF tuner block is presented for DAB/DAB+, DRM30/DRM+, and HD Radio digital radio standards. The developed chipset can receive broadcast from all standards and frequencies considered through simple software change.
