Fuzzy-Adaptive-PID

MATLAB的编程程序设计教案，很全很详细很强大，适合初学者(Programming Programming MATLAB lesson plans ，it is very strong, suitable for beginners)

在高斯信道下，采用16QAM,维特比编码的64子载波的OFDM系统(the Gauss channel, using 16QAM, Viterbi encoding of the 64 subcarrier OFDM system)

An ad-hoc network with a sender, a destination and a third station act- ing as a relay is analysed. The channels are modelled containing thermal noise, Rayleigh fading and path loss. Di® erent combining methods and di- versity protocols are compared. The amplify and forward protocol shows a better performance than the decode and forward protocol, unless an error correcting code is simulated. To combine the incoming signals the chan- nel quality should be estimated as well as possible. Information about the average quality shows nice bene¯ ts, and a rough approximation about the variation of the channel quality increases the performance even more.

基于短时傅里叶变换的非平稳信号的时频分析(Based on Short time fourier transform,signal s time-frequecy analysis.)

matlab中fplot与Plot的区别，希望对大家有所帮助。(matlab difference in fplot and Plot, we want to help.)

性指标的价值函数达到最小。FCM与HCM的主要区别在于FCM用模糊划分，使得每个给定数据点用值在0，1间的隶属度来确定其属于各个组的程度。与(indicators of the value of minimizing function. HCM FCM with the main difference is fuzzy FCM, broken down to make each set of data points with the value 0, one of the membership to determine its belong to the group level. And)

本程序先使用RSSI中对数常态模型来测距离，然后用三边测量法来计算未知节点的坐标。(The program first uses RSSI in lognormal model to measure the distance, and then use trilateration to calculate the coordinates of the unknown node.)

对实验采集数据进行线性处理，使得最后得到的实验结果近似于一条直线。(Linear processing of experimental data collection, so that the final experimental results obtained approximates a straight line.)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)
