Pełny tekst źródłaSpectrum sensing applications cover wide variety, such as efficient utilization of frequency spectrum, and in medical applications. The conventional architecture used by all the previous publications for spectrum sensing receiver is based on baseband ADC, hence it has high power consumption, higher complexity, and suffers from circuit mismatches and nonlinearity. In this work, we propose using an RF receiver based on bandpass delta-sigma ADC. It is much more convenient to have a tunable BP ΔΣ ADC to simplify the spectrum sweeping task. The previously reported tunable BP ΔΣ ADC’s are implementing tunability in a complex manner. We present an efficient implementation of tunable BP ΔΣ ADC with fixed ratio between the sampling frequency and center frequency. That fixed ratio further simplifies the implementation of the down conversion mixer and decimation filter which serve as the digital backend of the receiver. A spectrum sensing receiver, based on the power-efficient RF front end architecture proposed in this thesis, is also proposed. The proposed complete receiver does not suffer from I/Q imbalance that highly affect the spectrum sensing performance. Simulation results to show the circuit nonlinearity impact on the performance are presented. A circuit implementation of a digital backend of the proposed system is presented. This implementation comprises an efficient down conversion mixer, decimation filter, custom FFT block, and energy detection module. The implementation was validated on Altera FPGA using the on-chip logic analyzer via the SignalTab tool.Studies to show the impact of I/Q imbalance on spectrum sensing performance were previously published. Nevertheless, those publications presented only either analytical or simulation results. In this work, we present the first hardware measurement of the I/Q imbalance on spectrum sensing performance using a commercial SDR transceiver platform.In the medical field, we also present for the first time a study of the effect of RF-EMF exposure on neonates by performing a simultaneous acquisition of RF signals along with recording the physiological parameters of neonates. Using R-Studio, the stationarity of the signals to be correlated was checked, a transformation was performed on the non-stationary signals. Finally, cross correlation between the acquired RF signal (average of the whole spectrum or in a specific band) and each of the recorded physiological parameters did not show an observable impact of RF-EMF exposure on neonates
