利用阵列随机共振系统处理AM信号，比较处理前后的加噪信号波形，可以发现SSR系统具有抑制噪声的作用，(Stochastic resonance system using array processing AM signals, comparing before and after adding noise signal waveform, can be found SSR system has a noise suppression effect)

首先根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。然后根据长训练字的特性，进行相关运算，进行OFDM符号FFT窗口起始位置的估计。估计出FFT窗口的位置后，先在时域进行小频偏的估计，将两个长训练字进行小频偏补偿后，进行FFT运算，根据FFT运算的结果进行整数倍频偏的估计。这些参数估计完成后，就可以进行数据解调了。先对数据部分进行完整的频偏补偿，然后根据估计的FFT窗口位置进行FFT运算得到频域的数据，进行解调。然后在对应于导频的子载波位置上提取出导频信息，根据导频信息估计出剩余定时误差以及剩余的信道响应误差，将误差量送入环路进行跟踪。当收到所有数据后，重新回到信号到达检测状态，进行下一次信号到达的检测和信号接收。(First, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives. And then the characteristics of long training word, the correlation operation for the FFT window starting position of an OFDM symbol estimate. The estimated position of the FFT window, the first small frequency offset in the time domain estimation, the two long training word small frequency offset compensation, the FFT operation, the FFT result of the operation for integer frequency offset estimate. These parameter estimation is completed, the data can be demodulated on. The first portion of the data for a complete frequency offset compensation, and based on the estimated FFT window position of the FFT operation to obtain frequency domain data, demodulated. Then corresponding to the position of the pilot subcarriers are extracted on pilot inform)

.已知某炉温控制系统，要求温度保持在600℃恒定，针对该控制系统有以下控制经验： （1）若炉温低于600℃，则升压，低的越多升压越高； （2）若炉温高于600℃，则降压，高得越多降压越低； （3）若炉温等于600℃，则保持电压不变。 设模糊控制器为一维控制器，输入语言变量为误差，输出为控制电压。输入输出变量的量化等级为7级，取5个模糊集，试设计隶属度函数误差变化划分表，控制电压变化划分表和模糊控制规则表。 (Known for a temperature control system that requires a constant temperature is maintained at 600 ℃, the following control experience for the control system: (1) If the furnace temperature is below 600 ℃, the step-up, the more the higher the lower the boost (2) if the furnace temperature is higher than 600 ℃, the blood pressure, high blood pressure, the lower the more (3) If the furnace temperature is equal to 600 ℃, then keep the voltage constant. Set of fuzzy controller for one-dimensional controller, input linguistic variables for error, the output control voltage.
