Fractional delay filters are applied to a wide range such as communications, speech processing, echo cancellation, etc. 分数延迟滤波器广泛用于通信,语音处理,回声消除等。
Specially, one of the crystallization parameters-Avrami exponent n is fractional, and the fractional value of n is not constant in the temperature range studied. 反映在结晶动力学参数之一&Avrami指数不是整数,且随结晶温度发生变化。
From the zones of contact regimes it is shown that the fractional area of valve holes has no effect on the range of mixed-froth regime zone, but with decreasing fractional area this zone will shift towards the side of smaller inlet clear liquid height. 由操作状态区域图上表明,开孔率对混合泡沫区域的范围大小没有影响,但开孔率减小,混合泡沫区域向入口清液层减小的方向移动。
The fractional matched filter, based on the fractional Fourier transform, is proved to reduce the mismatch in range compression under some conditions. 证明了基于分数维Fourier变换的分数匹配滤波器在一定条件下对失配有抑制作用。
On basis of fractal theory and the principle of fractional Brownian motion, this paper puts emphasis on the following parts : Firstly, the determination of fractal non-scale range on calculate fractional dimension is discussed, which adopts method associated artificial cognition with track decision. 本文利用分形几何理论与分形布朗运动原理,重点研究和分析了以下的几个问题:分形维数计算时无标度区的确定,使用了人工法与轨迹法相结合的方法;
