To improve Digital Audio Broadcasting (DAB) receiver performance, we need to use better signal processing algorithm. However, it is impossible to modify the signal processing algorithm in DAB commercial hardware. In addition, the notebook PC based software radio research platform allows convenient acquisition of the massive radio data at variant environments and online analysis with variable signal processing procedure more easily. We have developed the first prototype portable software radio research platform for DAB which consists of a USB RF receiver module, USB interface and PC based software for device controlling and signal processing. Iterative decoding and ICI cancellation are also added to improve the performance in mobile channels.
