In this work, first real hardware implementation results of CDR (Compressive Digital Receiver) are detailed. CDR is a digital receiver technology, which estimates frequency, amplitude, pulse-width etc. parameters of the incoming signal without ambiguity in frequency, by sampling the signal at rates far below the Nyquist limit based on compressive sensing theory. It is observed that the implemented hardware structure can resolve an instantaneous bandwidth of 2 GHz by using only two ADCs (Analog to Digital Converter) running at 200 MHz sampling frequency. It is argued that the CR system can be used as a digital receiver especially for Electronic Support Systems since it can monitor a wide spectrum by sampling at a very low rate.
