<p><b>Nouvelle page</b></p><div><br />
==Introduction==<br />
This article shows that it is possible to generate and transmit a DAB, DAB+, or T-DMB signal using a recent PC running Linux and a software radio peripheral. This is not intended for pirate DAB but for testing, development, experimentation and also demonstration that DAB technology is not as complex as some like to say.<br />
<br />
The function from the audio encoder, service multiplexer, ensemble multiplexer and COFDM modulator are performed in software on the CPU from the PC. The result is baseband complex samples from the DAB/DAB+/T-DMB signal that can then be played on a hardware radio peripheral (the equivalent of a soundcard but for radio frequencies) for transmission at desired radio frequency. <br />
<br />
==Equipment==<br />
<br />
For this experiment such a configuration was used:<br />
<br />
===Hardware===<br />
*Pentium IV 2.4 GHz PC, 512MB memory, USB2 interface<br />
*Universal Software Radio Peripheral (USRP) from [http://www.ettus.com/ Ettus] (~700$)<br />
**Basic TX daughterboard (~75$)<br />
<br />
===Software===<br />
*[http://www.ubuntu.com/ Ubuntu] Linux Feisty (or higher)<br />
*'''[http://mmbtools.crc.ca/ CRC MMBtools]: the software implementation of DAB/DAB+/T-DMB from CRC Research Center in Canada''' <br />
