For accurately identifying the distribution charac-teristic of Gaussian-like noises in unmanned aerial vehicle(UAV)state estimation,this paper proposes a non-parametric scheme based on curve similarity *** the framework of the pro-posed scheme,a Parzen window(kernel density estimation,KDE)method on sliding window technology is applied for roughly esti-mating the sample probability density,a precise data probability density function(PDF)model is constructed with the least square method on K-fold cross validation,and the testing result based on evaluation method is obtained based on some data characteristic analyses of curve shape,abruptness and *** com-parison simulations with classical methods and UAV flight exper-iment shows that the proposed scheme has higher recognition accuracy than classical methods for some kinds of Gaussian-like data,which provides better reference for the design of Kalman filter(KF)in complex water environment.

作者： Zhangming zhu Jun CHANG hongzhi liang Ruixue DING Shubin LIU Institute of Integrated Circuits Xidian University

With the recent explosion in interactive machine learning and artificial intelligence, the ultra high-speed wireline or optical data links are evaluated as a crucial device that is handling the ever-growing data traffic in high-performance computing environments [1, 2]. In practice, high-order modulation strategies, such as four-level pulse-amplitude modulation(PAM4), enable a significant increase in throughput without raising the baud(Nyquist) rate in transceivers.
