A NSZT Method for Frequency Estimation and Anti-noise Performance Analysis
Chinese Journal of Electronics（2018）
摘要
Among all the frequency estimation algorithm, the spectrum zooming method has superiority for high resolution and excellent anti-noise performance, but it needs more computational resource. The typical spectrum zooming methods include Zoom fast Fourier transform (ZFFT), Chirp-Z transform (CZT) and zeropadding, which are all uniform spectrum zooming methods. A Nonuniform spectrum zooming transform ...
