Overview

CRC-DABMOD is a DAB/DMB software modulator developed at CRC over several years as an experimental tool to support activities is the area of mobile multimedia broadcasting (MMB). In February 2010, CRC released CRC-DABMOD as a free open source software project under a GPL license.

The easiest way to try CRC-DABMOD is to download and use the CRC mmbTools live CD .

Description

Over the years, CRC-DABMOD has become a flexible and stable platform for the development and testing of new DAB applications and services. It is also a very useful tool for application and receiver functionality testing and as a portable demonstration platform. CRC-DABMOD is a basic SDR modulator that implements the DAB specification. It is based on the USRP platform which provides D/A conversion and RF components for the transmission/reception of signals in different bands. The waveform is generated on a PC platform and transferred via a USB interface to the D/A subsystem. Although CRC-DABMOD was not originally intended for 24/7 commercial operations, it proved very reliable over the last 5 years where it has been used extensively as the main modulator for internal laboratory experiments and public demonstrations worldwide.
