PDCCH的实现过程及其遇见的问题应该遇见的问题(PDCCH the realization of the process and the issue should be met to meet the problem of)

用贝塞尔曲线画圆的代码,效率高，可以调节参数控制(draw circle by bezier )

二维，ＦＤＴＤ，ＰＭＬ，Ｍａｌａｂ语言。(Vacuum point source radiation, two-dimensional, FDTD, PML, Malab language.)

反馈控制材料加上matlab仿真，很好地学习材料(Feedback control materials plus matlab simulation learning materials)

在本文件中提供了总声压级，声压级等的计算(determination of loudness level)

2D PCA IS METHOD USED FOR IRIS AND FACE RECOGNITION AN INTERSETING METHOD

在自适应信号的理想输入为有正弦信号。噪声输入也为一正弦信号。它们相互迭加，再经过LMS自适应算法，再比较它们的结果。(In an ideal adaptive signal has sinusoidal input signal. Noise input for a sinusoidal signal. Their mutual superposition, and then after LMS adaptive algorithm, and then compare their results.)

维纳噪声抑制，1、 实验原理是利用信号之间的相关性进行信号估计，从而将噪声滤除； 2、 辅助观测信号的噪声抑制可利用Wiener-Hopf方程 求出维纳滤波器的系数 ，式中 是 的自相关阵， 是输入信号 和滤波器输入 之间的互相关矢量； (Wiener noise suppression, 1, experiment is the use of the correlation between the signals for signal estimation, which will filter out the noise 2, the auxiliary noise suppression observed signal Wiener-Hopf equation can be obtained by Wiener filter coefficients, where is the autocorrelation matrix, is the input signal and filters the cross-correlation between the input vector )

我学习信号系统时原创的用matlab实现的谐波提取 ，两种方案，先分频再提基波，或者利用带通滤波器(I study the signal system to achieve an original harmonic extraction using matlab, the two programs, the first frequency and then Ti Jibo, or the use of band-pass filter )

输入两个整数，当前一个数不小于后一个数是，输出1和两数之差；当小于时，输出0和第一个数。(Enter two integers, a number not less than a number, output 1 and the difference of two numbers when less than output 0 and the first number.)
