Modular Software Radio
The idea of this project is quite old, and different people tried to hack things together. The main characteristics of this implementation are the following:
Our Definition of Software Radio
We talk about Software Radio when the map between the data (sending and receiving) and the data-carrying antenna signal are completely (within hardware limits) specified by the software. Any map that conforms with the hardware limitations (power, bandwith, hardware imperfections) may be implemented by means of an appropriate code.

Of course, the documentation is not complete yet, and I hope it will never be,as this is an ongoing project. Either go to the HTML-version of the documentation, or download the PS-file of the documentation. After reading this, you can make up your mind whether it's worth to continue looking at this project.
We have now a running 4x4 antenna system using custom-designed cards from Radio Innovation together with some high-quality A/D and D/A cards from ICS-LTD. Because of the limit of the PCI-bus we currently only get a bandwith of about 2MHz.
