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.   Analysis of quantitative differences in large-aperture size for free-space optical communication systems with circle polarization shift keyin (CPCI-S收录) 会议论文 INFRARED, MILLIMETER WAVE, AND TERAHERTZ TECHNOLOGIES 作者:  Liu, Chao[1];  Yu, Xuelian[1];  Yao, Yong[1] 收藏  |  浏览/下载：1/0  |  提交时间：2019/04/16 bit-error rate  atmospheric turbulence  free-space optical communication  circle polarization shift keying  on-off keying  large-aperture  Gamma-Gamma distribution   Theoretical Noise Performance of SIMO-DCSK Communication Schemes 会议论文 IEEE Symposium on Wireless Technology and Applications (ISWTA), Kuching, MALAYSIA, 2013 作者:  You, Na;  Yi, Bo;  Wang, Shilian 收藏  |  浏览/下载：2/0  |  提交时间：2020/01/05 differential code-shift keying (DCSK)  bit error rate (BER)  single-input multiple-output (SIMO)  the non-central F distribution   Theoretical Noise Performance of SIMO-DCSK Communication Schemes 会议论文 2013 IEEE SYMPOSIUM ON WIRELESS TECHNOLOGY & APPLICATIONS (ISWTA2013), 134-137, 2013 作者:  You, N;  Yi, B;  Wang, SL 收藏  |  浏览/下载：2/0  |  提交时间：2020/01/05 differential  code-shift  keying  (DCSK)  bit  error  rate  (BER)  single-input  multiple-output  (SIMO)  the  non-central  F  distribution
