波函数

The characteristic functions are now depending on frequency, real plate wave number and imaginary plate wave number.

现在的特征函数依赖于频率、实波数和虚波数。

We use a different transmission method where binary Golay complementary pairs are sent simultaneously on the inphase and quadrature parts of the subcarrier, and compare the performance with existing method. Using our method, the radar obtains a pair of Golay sequences from only one echo, which reduces the ambiguity function sidelobes when the reflected signals are partially received, and fully exploits the property of Golay pairs.

我们采用将二位元格雷互补对以复数组合，发射时以调变正交载波的方式同时传送，并且将一个时段同时传送格雷互补对之方式，与一个时段仅传送一个二位元格雷互补序列比较，可使雷达仅接收一个回波即可得到一对格雷互补序列，以降低回波部份接收时之混淆函数旁峰，使格雷互补对之特性充分发挥。

Calculating formula of wave impedance is obtained by main values of the inverse tangent function of phase_shift at two neighboring frequencies and the corresponding integral character of phase_shift is denoted as the convergent criterion of wave impedance inversion.

利用复合反射系数中多个频率点的相移反正切函数主值，给出了波阻抗的计算公式，并把套管-地层环空间介质中波的相移的整、实特性作为波阻抗反演收敛的判据。

In this paper, we firstly introduce some basic properties of wavelet, which are involved in chapter one .secondly, we introduce orthogonal wavelet bases, scale function and scale equations etc.,which are involver in chapter two .

本文首先介绍了傅里叶变换和小波变换的由来以及一些基本性质，这主要体现在第一章，随后介绍了正交小波基以及尺度函数，尺度方程等概念，这主要体现在第二章。

M. Johnstone, a method integrated with an improved threshold function and 2-D wavelet transform, is used to overcome the shortcoming of discontinuity of hard-threshold method and dispersion of the soft-threshold method.

M。 Johnstone提出的多分辨分析小波阈值去噪方法的基础上，用一种改进的闺值函数和二维小波变换相结合的方法，克服了硬阈值法不连续性和软阈值法有偏差的缺点。

Wavelet transform can be seen as translating an image into coordinate of orthogonal basis.

从函数正交分解的角度看，小波变换可以看作把图象的象素点转换成一系列正交小波基的坐标或者说是投影，每个坐标对应着这些基的能量大小。

This paper discusses how to design optimal orthogonal wavelet and scaling functions which are generated by FIR filters, from the view point of bandwidth efficiency, the designing method and results are given in details.

以往研究较多的是Daubechies和Battle-Lemarie小波系列，本文从频谱利用率的角度出发，讨论如何设计用FIR滤波器实现的最佳正交小波和尺度函数，给出了设计方法和结果。

The symmetric property and compact support are incompatible for orthogonal wavelets in function space, whether the properties of discrete orthogonal wavelets can be compatible is still unknown.

函数空间中正交小波的对称性和紧支性不能兼容，而离散空间中正交小波的性质能否兼容仍然是一个未知的问题。

The practical employment of multidimensional wavelet is only limited to tensor product wavelet. To construct a tensor product orthonormal wavelet basis in L〓, 2〓-1 different mother wavelets are used, and thus storing and computing wavelet basis of large dimension are of prohibitive cost.

根据Meyer的小波基存在性定理，利用张量积方法构造L〓的一个规范正交小波基，需要2〓-1个不同的函数，存储和计算方面的开销太大，在实时应用方面尚有很大的局限性。
