Project abstract
Technological innovation can be dealt with by small enterprises, if it is properly supported by qualified research centers. This idea backs the project, which aims at realizing, on an FPGA, a demodulator capable of analyzing the terrestrial digital television signal (DVB-T). Obviously, commercial chips that demodulate the DVB-T signal do exist, however there are niche applications where commercial chips are non adequate. Nowadays, these applications, which have always been developed by small and medium enterprises, require a degree of technological innovation that can hardly be autonomously reached by small enterprises. Indeed, the necessary know-how is typically only available in large enterprises or in research groups working in large institutions such as, in this case, the Department of Electronics and Information of the Politecnico di Milano. The project is finished.
Project results
The result is the development, in the VHDL programming language properly mapped onto an FPGA, of a DVB-T demodulator and signal analyzer. A prototype, developed using a commercial evaluation board, is available at the DEI modem laboratory. The prototype receives IF signal at 36 MHz and allows the performance verification of the demodulator. The customer enterprise obtained the first place in a public call by the City of Milan, out of about 1000 applications.
