杭州电子科技大学数字信号处理课件第7章 FIR数字滤波器的设计方法。
A method of computing the finite-horizon control inputs for FIR plants whose parameters are only known to lie in a set is proposed. The parameter set is assumed to be described by an ellipsoidal bound...
We consider the design of finite impulse response (FIR) filters subject to upper and lower bounds on the frequency response magnitude. The associated optimization problems, with the filter coefficient...
Robust Chebyshev FIR equalization     Impulse response  filter  frequency and function       font style='font-size:12px;'> 2015/8/10
In Chebyshev finite-impulse response (FIR) equalization, we design an FIR filter that minimizes the Chebyshev equalization error, i.e., the maximum absolute deviation between the equalized and the des...
We have identified a complete, flux-limited (S 160>120 mJy) sample of 160 μm selected sources from Spitzer observations of the 1 deg2 Infrared Space Observatory (ISO) Deep Field region in the Lockman ...
The contemporary genetic structure of species offers key imprints of how organisms responded to past geological and climatic events, which have played a crucial role in shaping the current geographica...
The magnetic field in the NGC 2024 FIR 5 dense core     individual  ISM  magnetic fields  Polarization  Stars  formation  Techniques  interferometric       font style='font-size:12px;'> 2010/11/10
We used the Submillimeter Array (SMA) to observe the thermal polarized dust emission from the protostellar source NGC 2024 FIR 5. The polarized emission outlines a partial hourglass morphology for the...
We extend the Unified Radio Catalog, a catalog of sources detected by various (NVSS, FIRST, WENSS, GB6) radio surveys, and SDSS, to IR wavelengths by matching it to the IRAS Point and Faint Source cat...
通带可调相位 FIR 数字滤波器及其设计     通带可调相位  FIR  数字滤波器       font style='font-size:12px;'> 2009/9/18
常见的 FIR 数字滤波器大致可分为两类:一类是线性相位滤波器;另一类是极小相位滤波器,这两种类型的滤波器,其相位响应均不可调.第一种滤波器,其群延迟为((N-1)T)/2,其中 N 为滤波器长度,T 为采样周期.以 N=60,T=0.2秒的线性相位滤波器为例,它的相位响应为...
The MERLIN model was applied on the results of a field-scale manipulation experiment with decreased nitrogen (N) deposition in an N saturated forest ecosystem in the Netherlands. The aim was to invest...
This study focuses on spatial variability of throughfall water and chemistry and forest floor water content within a Douglas fir (Pseudotsuga menziesii, Franco L.) forest plot. Spatial patterns of wat...

GM-RC,AJ-RC FIR系统辨识方法的改进     高阶累量  非最小相位FIR系统  参数估计       font style='font-size:12px;'> 2008/12/31
本文讨论基于高阶累量辨识非最小相位FIR系统问题.在文献[1,2]提出的GM-RC, AJ-RC算法的基础上,提出了一种改进算法.模拟实验结果表明:改进算法有效地抑制了传 播误差并进一步简化了运算,因而性能更加优越.
非最小相位FIR系统的自适应辨识     自适应系统辨识  非最小相位系统  高阶累量       font style='font-size:12px;'> 2008/12/26
提出了一种基于线性代数方程组约束和梯度法的非最小相位FIR系统的自适应辨 识算法.选用的线性方程组具有列满秩的系数矩阵,保证了系统参数的唯一可识别性.由于只 采用高阶累量,故能够抑制任何高斯有色噪声的影响.重点讨论了梯度法中步长的选择,提出 了收敛速度最快的变步长.仿真实验的结果证实了算法的有效性.
