SDR - Receiver Platform for development and research

The SDR Receiver Platform is a development environment for study by students, for improvements or just for demonstrating this new concept for future communications channels (GSM, professional or amateurs communications, satellite or new digital concepts). The Receiver Platform was implemented using the SDR (Software Defined Radio) technology, presented as a platform for research and development. Actual receiver is intended to use the digital quadrature demodulation for narrow band FM broadcasts for 2METER band (145MHz designed for radio amateurs).With this new concept is easy to implement other operating modes: analog (Single Side Band, Amplitude Modulation, etc) and digital (Frequency Shift Keying, Phase Shift Keying, Quadrature Amplitude Modulation, etc.). With this platform is very easy to use other bands or modes of working just by modifying the software- firmware. It doesn´t require major hardware changes, resulting a reliable and flexible system. Modular system is achieved both physically and functionally; adaptability to different situations is important for a cost efficient solution.
