Parameter Estimation of Multiple Linear Frequency Modulation Signals Sensed by Nyquist Folding Receiver Using Periodic Linear Frequency Modulation Local Oscillator

Abstract: The Nyquist folding receiver (NYFR) is a new ultra-wideband (UWB) sensing structure that can sense signals in an UWB space. Since linear frequency modulation (LFM) signal is widely used in ...
