PID
在PID控制中，微分信号的引入可改善系统的动态特性，但也易引起高频干扰。在误差扰动突变时尤其显出微分项的不足。若在控制算法中加入低通滤波器，则可使系统性能得到改善。(In PID control, the introduction of differential signal can improve the dynamic characteristics of the system, but it can also cause high-frequency interference. When error perturbations change abrupt, the deficiency of differential terms especially shows. If the low-pass filter is added to the control algorithm, the performance of the system can be improved.)

QRcode
QR码作为一种可高速、全方位识别的二维条码,已经在各行各业中得到了应用,并具有很大发展潜力.本文针对QR码图像的识别过程中可能遇到的图像噪声干扰、QR码占实际拍摄图像的一部分、倾斜、几何失真等问题进行了研究,提出了通过改进型中值滤波去除噪声,使用QR码符号特性定位并对倾斜图像进行旋转,对失真不严重的图像采用控制点变换和双线性插值方法进行几何校正.实验证明, 本文的方法简单有效, 可以用于提高条码的正确识别率.(As a high-speed, full identification of the two-dimensional bar code, QR code has been applied in all walks of life, and also has great potential for development. In this paper, aiming at QR code image recognition process may be encountered in noise interference, QR code accounting for the actual captured image just a part, slant, geometric distortion, and other issues have been studied, put forward through improved median filter to remove noise, use QR code symbol characteristics to locate and rotate the tilted image, distortion which is not serious use control-point transform and spatial bilinear interpolation method for geometric correction. The results show that this method is simple and effective, can be used to improve the QR code correct recognition rate.)

mod_and_dem_ask
Modulation and demodulation ASK. At the beginning, we create the digital signa (1 and 0), after we do the modulation, add noise and demodulation. At the end we do the reconstruction of the signal.

IEEE80211a
The 802.11 standard specifies a carrier sense multiple access with collision avoidance(CSMA/CA) protocol. In this protocol, when a node receives a packet to be transmitted, it first listens to ensure no other node is transmitting. If the channel is clear, it then transmits the packet. Otherwise, it chooses a random "backoff factor" which determines the amount of time the node must wait until it is allowed to transmit its packet. During periods in which the channel is clear, the transmitting node decrements its backoff counter.
