Recovering IFS Interpolated Signal from Noise ── A New Simple Inverse Problem Solver Fractal Theory 噪声中的分形插值信号提取&分形逆问题的一种简便解法
Firstly, the autocorrelation function of large time lag is interpolated to the section of small time lag with complex exponential algorithm and the estimation of the autocorrelation function of small time lag for a narrow-band signal is obtained. 本文首先用复指数近似方法,将大延时相关函数内插,得到窄带信号分量的小延时部份的相关函数的估计值。
For example, four kinds of decimated structure and interpolated masks for 1/ 4 and 1/ 8 decimated image signal are also shown in this paper. 以1/4和1/8抽取为例,研究了二种1/4抽取和二种1/8抽取的图象信号,分别给出了这四种抽取结构的内插模板。

Besides, we use interpolated Doppler compensation algorithm to compensate the Doppler frequency sidelobe for Barker code and M sequence with different signal to noise ratio. Then we calculate the peak sidelobe level and sidelobe level points. 然后介绍了二相编码信号的多普勒补偿技术,接着用内插多普勒补偿算法对不同信噪比的巴克码,M序列的多普勒频移给予补偿,以及计算峰值旁瓣电平和积分旁瓣电平。
