Abstract
Nyquist Folding Receiver is a novel reconnaissance receiver structure which is able to use single ADC to sample Ultra-wideband signals. And the Synchronous Nyquist Folding Receiver (SNYFR) is an improved structure of NYFR. When input is multicomponent single-frequency signal, with the consideration of the characteristics of the output we propose an algorithm of Nyquist Zone(NZ) judgment and parameters estimation based on scaling search in Fractional Fourier Transform (FRFT) domain to avoid detection error occurring when the input signal components locate in the NZ fuzzy area. Computer simulation show that when SNR beyond, the Probability of Correct Decision(PCD) of signal detection can be achieved 100% and the mean square error of parameters estimation can be approached Cramer-Rao Bound(CRB) simultaneously.
