有两个代码文件，是分别计算微带贴片天线设计时背馈和侧馈两种情况下的天线尺寸的，很全很精确！(There are two code files, which separately calculate design of microstrip patch antenna fed back and the side-fed both cases, the antenna size, it is all very precise!)

基于拉格朗日插值法的可变分数延时滤波器比较图，通过比较不同的分数时延时的滤波器特性来观察分数延时滤波器的性质与限制(Lagrange interpolation method based on variable fractional delay filter comparison chart, filter characteristics by comparing the scores of different delay time to observe nature and limitations of fractional delay filter)

基于MATLAB的遗传算法工具箱，英国Sheffield大学推出的，内容上覆盖GAOT，影响较广，较为完备。( Genetic algorithm toolbox based on matlab was developed by Sheffield University of UK.Because its content covered GAOT, it is used widely.)

非持续性CAMA是一种冲突避免的CSMA协议，如果终端检测到信道状态空闲，则立即进行数据传输，而信道状态忙，则停止载波监听，并随机在等待一段时间后再进行载波监听。(Non-durable CAMA avoid CSMA protocol is a kind of conflict, if the end channel state idle, detected immediately for data transmission, the channel state is busy, stop the carrier sense, and random carrier sense of the reentry after waiting for a period of time. )
