矩量法求半波振子天线的阻抗,与理论值偏差较小，比较精确(mom to calculate the z of the antenna)

实现各阶本原多项式的小m序列的长生，通过改变本原多项式的生成矩阵可以产生想要的m序列的(Order to achieve the small-m primitive polynomial sequence longevity, by changing the primitive polynomial generator matrix m can produce the desired sequence)

仿真包含有4个散射点的目标的转台ISAR成像(simulate ISAR imaging of target including four scatters)

本算法用来实现图像的首数字规则特性，首数字规则在1881年就被发现，他能检测图像的所有像素点的AC系数是否符合首数字规则(The first algorithm is used to achieve image characteristic figure rule, the first rule number 1881 was found that he can detect all the pixels in the image whether the First Digital AC coefficient rules)

此程序为Gring通用EMD2007之后的版本，其对2003版做了改进，一个程序文件就可以实现EMD的分解(This program for version the Gring General EMD2007 after the 2003 version has been improved, a program file can be achieved EMD decomposition.)

Orthogonal frequency division multiplexing (OFDM) is becoming the chosen modulation technique for wireless communications. OFDM can provide large data rates with sufficient robustness to radio channel impairments. Many research centers in the world have specialized teams working in the optimization of OFDM for countless applications. Here, at the Georgia Institute of Technology, one of such teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part of the Georgia Center for Advanced Telecommunications Technology (GCATT). The purpose of this report is to provide Matlab code to simulate the basic processing involved in the generation and reception of an OFDM signal in a physical channel and to provide a description of each of the steps involved. For this purpose, we shall use, as an example, one of the proposed OFDM signals of the Digital Video Broadcasting (DVB) standard for the European terrestrial digital television (DTV) service.

1．产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计三种高通， 低通，带通滤波器对信号进行滤波处理，观察滤波后信号的频谱。 2.采集一段含有噪音的语音信号（可以录制含有噪音的信号，或者录制语音后再加进噪音信号），对其进行 采样和频谱分析，根据分析结果设计出一合适的滤波器滤除噪音信号(1. Produce a continuous signal, including low-frequency, medium frequency, high-frequency components, its sampling, spectral analysis, are designed for three high-pass, low pass, band-pass filter the signal filtering treatment to observe the signal spectrum after filtering. 2. Acquisition section of the speech signal contains noise (can record a signal containing noise, or voice recording, additional noise after the signal), its sampling and spectral analysis, based on an analysis of the results to design a suitable filter to filter out one noise signal)
