The Information Theoretic Approach to Signal Anomaly Detection for Cognitive Radio

Figure 15

Block diagram of the hardware test-bed. The E4438C ESG signal generator produces the signal under test in both analogue and digital formats. The digital signal is passed to the FPGA platform via the N5102A digital signal interface module while the analogue signal is fed into the oscilloscope. The trigger signal from the FPGA core is also connected to the oscilloscope via a digital probe for comparison.
