However  as FSK is non-linearly modulated  parameter estimation with high accuracy is hard to realize. Based on the spectrum analysis complement with time-frequency distribution  a highaccuracy FSK signal parameter estimation algorithm is put forward in this paper. According to the signal characteristics  under-sampling and ZFFT are used to improve the accuracy of spectrum analysis  and the base frequency resolution meets system requirement of 0.02Hz. Wigner-Ville distribution has an excellent time-frequency concentration while serious cross-term interference at the same time. Through the design of kernel function  the cross-terms are almost suppressed and the upper/down side frequency resolution meets the system requirement of 0.2Hz. The effectivities of all the methods mentioned above have been proved by MATLAB simulation  which pave a solid way for the development of high-accuracy FSK signal parameter estimation devices. 2008 IEEE.   The Calculation of Cumulative Distribution Function of Water Vapor Using Modified Bandwidth 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 2002, 卷号: 11, 期号: 1, 页码: 16,20 Yuhong Nie; Haigeng Chen 收藏  |  浏览/下载：6/0  |  提交时间：2013/03/12 gas radiation  cumulative distribution function  bandwidth.   Nonparametric estimation of quantile density function for truncated and censored data 期刊论文  OAI收割 JOURNAL OF NONPARAMETRIC STATISTICS, 1999, 卷号: 12, 期号: 1, 页码: 17-39 作者:  Zhou, Y;  Yip, PSF   |  收藏  |  浏览/下载：16/0  |  提交时间：2018/07/30 quantile density function  truncating and censoring  kernel estimator  random bandwidth  nearest neighbor estimator  optimal bandwidth
