High Frequency Resolution Adaptive Thresholding Wideband Receiver System

Abstract Details

2015, Master of Science in Engineering (MSEgr), Wright State University, Electrical Engineering.
Fast Fourier transformation (FFT) is widely used in wideband digital receivers to detect multiple signals. To achieve high dynamic range, the receiver has to increase analog-to-digital (ADC) resolution bits, which requires significant computation time and therefore increases receiver time resolution. The other challenge of FFT approach is two signals with a small frequency difference (i.e., less than five FFT frequency bins in most cases) cannot be detected simultaneous. This thesis presents an adaptive thresholding wideband digital receiver to accurately detect two simultaneous high dynamic range signals even when they are close to one FFT frequency bin. The receiver can perform well for more than two input signals if the requirements for the receiver frequency resolution and dynamic range are reduced. The receiver design architecture and performance evaluation are presented.
