作为信号的

In Chapter 2, the basic knowledge of higher—order spectra is introduced. The relationship of higher—order cumulants and higher—order spectra between input and output of a linear—time—invariant system driven by a non—Gaussian process is analyzed.

本论文的目的在于，以高阶统计量作为信号处理的工具，研究非最小相位随机信号建模以及噪声中的谐波恢复问题。

In the described system, in order to transmit the narrow-band analog signals or low speed digital signals at any time and under any climatic condition, sun-blind-region ultraviolet is used as information carrier, the modulated low voltage mercury-vapor lamp is used as emission device.

所描述的系统是以日盲区紫外光作为信息载体的，用被调制的低压汞蒸汽紫外放电灯作为发射器件，以日盲型滤光片和光电倍增管或日盲型紫外光电倍增管作为接收器件，以达到在任何时间和在任何气候下完成窄频带模拟或低速数字信号的传输。

As the address of EEPROM, which was used for looking2up table, the information of octant and signals of magnetic encoder which were converted by A /D converterwere dealt by FPGA. And the frequencymultip lication formagnetic encoderwas comp leted. So the resolution and accuracy ofmagnetic encoderwere imp roved, 4096 multip le frequencies can be achieved in per cycle.

同时利用FPGA对卦限信息和磁编码器输出信号的A /D转换信息进行处理，作为EEPROM的地址信息进行硬件查表，实现对磁编码器信号的倍频处理，从而提高了磁编码器的分辨率和测量精度，可实现每个周期4 096份的倍频。

I was encouraged with this, and as I had my patroon's antient on board, I made a waft of it to them for a signal of distress, and fir'd a gun, both which they saw, for they told me they saw the smoke, tho' they did not hear the gun

这给了我极大的鼓舞。我船上本来就有我们原主人的旗帜，我就拿出旗帜向他们摇起来作为求救的信号，同时又鸣枪求救。这两个信号他们都看见了，因为，后来他们告诉我，枪声他们虽然没有听到，但看到了冒烟。到中国译典经典版本中查找关于waft的最新解释和例句。。。。

In this paper, some problems that have to be faced with in the application of SPLL to static synchronous compensator are analyzed, and two improvements of SPLL are proposed. The first one is removing the filtering function of lead-leg element into the prepositive delayed signal cancellation element to remedy the difficulty in deciding its parameters; the second one is directly taking the post-PI regulation output of q-axis voltage as error signal of phase to call off the forward integrating element.

分析了软锁相环应用于静止同步补偿器时面临的若干问题，并提出了2方面的改进方案：一是针对超前/滞后环节参数选取困难的问题，将其滤波功能转移到前置延时信号消除环节中；二是q轴电压经PI调节的输出直接作为相位的误差信号，减少了前向积分环节。

ABSTRACT The purpose of this dissertation is to study the problem of modeling of non—minimum phase random signals, and the retrieval of harmonics in noise by using higher—order statistics as a signal processing tool.

Control layer and parameter layer represent the available number of rows and the concrete value of the available rows of separation matrix respectively. Non-Gaussian was used to measure the independence of the stochastic signals. The kurtosis was maximized/minimized by searching a linear combination of observation signals, and then the independent variables were separated.

用控制层、参数层分别表示分离阵有效行数和有效行数的具体数值，将非高斯性作为随机信号相互独立的度量，通过寻求观测信号的一个线性组合，使其峭度最大化或最小化来分离独立分量。

This system includes three units of signals' sample,processing, and display.

本文设计了以DSP作为中央处理器的数字电路系统，包括信号的采集、处理、显示三个单元，实现了对整个系统的控制与信号处理。

The false operation and the operation of removal pineal gland were carried out at 1 month before the Winter Solstice and the Summer Solstice each year, rats were bred after the operation and were decollated at night on the Winter Solstice and the Summer Solstice.

2.2 实验研究：(1)总体设计：本实验研究主要以与&肾应冬，主生殖&相关的性腺轴和对光节律极为敏感的松果腺为切入点，选择了在细胞信号转导途径中起重要作用的G蛋白和受体分子，以及在细胞信号转导末端的基因表达作为研究的对象。

Preprocessing consists of data selection, baseline adjustment, noise filtering and peak identification. Data selection removes preprimer data section which contains little useful information. Baseline adjustment adjusts the baselines of four channels to the same level. Noise filtering removes the impulse noise and white noise. Peak identification selects the peak data for use in cross matrix determination.

预处理包括数据段选取、基线调整、噪声滤除、峰值识别四个模块：数据段选取删除前段冗余数据；基线调整使得四色荧光信号的基线高度一致；噪声滤除去除信号中的脉冲噪声和白噪声；峰值识别选取峰值数据，作为求解串扰矩阵的数据。
