北工大matlab电子课件，陆续还有好多，很全的，希望大家下个痛快(err)

基于最小生成树的最小连通支配集的一种优化算法(Based on minimum spanning tree of a minimum connected dominating set algorithm)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)

阵列天线多端口的馈电操作。在进行波束赋形或相控阵天线设计时，若天线端口数量巨大，可以用该程序一次实现对所有天线端口相位及赋值的输入。(Multi-array antenna feed port operations. Performing beamforming or phased array antenna design, if the huge number of antenna ports can be used to implement the program once all the input phase and the antenna port assignment.)

去斜处理（宽带的匹配滤波）Stretch方法是针对线性调频信号而提出的， 其方法是将输入信号与参考信号 （经适当延迟的本振信号， 延迟量通常由窄带信号测距结果估计出） 混频 ，则每一个散射点就对应一个混频后的单频分量，对混频输出的信号进行 DFT 处理 ，即可获得目标的距离像，对参考信号的要求是应具有与输入信号相同的调频斜率。(dechirp matched filter Stretch method is proposed for linear frequency modulation signal. It mixes the input signal with the reference signal (local oscillator signal with appropriate delay, the delay is usually estimated from the result of narrowband signal ranging). Then each scattering point corresponds to a single frequency component after mixing, and DFT is performed on the mixed-frequency output signal. The range profile of the target can be obtained by processing, and the reference signal is required to have the same frequency modulation slope as the input signal.)
