A common SDR platform for digital audio broadcasting system

摘要

It is envisioned that all broadcasting systems will be digitalized in future. New services and more information require high data rates for broadcasting systems. There are many digital audio broadcasting standards in the world, such as DAB (Digital Audio Broadcasting) in Band III and Band L, DRM (Digital Radio Mondiale)and HD Radio in AM band and FM band. In this paper, we will present a general purpose SDR (Software Defined Radios) platform to realize digital audio broadcasting systems, including transmission and reception. In the platform, we not only can test novel digital technologies but also experiment with different service modes.
