关于OFDM多智能体下的功率分配，并与注水法做了比较(OFDM on multi-agent of power allocation, and with the water injection method were compared )

超声相控阵仿真论文，研究了超声声束的指向性、声压等特性，以及探头设计准则。(Ultrasonic phased array simulation thesis, studies the ultra sound beam directivity, pressure characteristics, as well as the probe design criteria.)

Matlab FFT分析，很好很强大，可以代替分析(Matlab FFT analysis, very good very powerful, can replace the analysis of)

shunt active filter

本代码应用FDTD 方法模拟微带带阻滤波器，并得到S11，S12 曲线以及显示电磁波在空间的传播。频率范围为0-20GHz。微带基片的相对介电常数为6.15，厚度是1.27mm。(Application of FDTD method to simulate the code microstrip band-stop filter, and get S11, S12, and the curve shows the spread of electromagnetic waves in space. Frequency range of 0-20GHz. Microstrip substrate relative dielectric constant of 6.15, the thickness is 1.27mm. )

在一定的约束条件下，其输出与一给定函数（通常称为期望输出）的差的平方达到最小，通过数学运算最终可变为一个托布利兹方程的求解问题。维纳滤波器又被称为最小二乘滤波器或最小平方滤波器，目前是基本的滤波方法之一。维纳滤波是利用平稳随机过程的相关特性和频谱特性对混有噪声的信号进行滤波的方法，1942年美国科学家N.维纳为解决对空射击的控制问题所建立，是40年代在线性滤波理论方面所取得的最重要的成果。(Under some constraint conditions, the output with a given function (often referred to as expected output) the square of the difference between the minimum, through mathematical operation can be turned into a final taub Leeds equation to solve the problem.Wiener filter is also known as least squares filter or least square filter, is now one of the basic filter method.Wiener filtering is to use the related characteristics of stationary random process and spectrum characteristics of mixed with noise signal filtering method, scientists in the United States in 1942 n. wiener established to solve the control problem of empty shooting, is 40 s in the theory of linear filtering is the most important results.)
