说明: 实现匹配滤波仿真的两个程序,每个程序生成四个图,可以通过比较验证信号的时延不影响匹配滤波的输出信噪比,及不同信号信噪比与信号波形无关,只与信号能量有关(Matched filter to achieve the two simulation procedures, each of the programs to generate the four plans, you can verify by comparing the signal delay does not affect the matched filter output signal to noise ratio, and different signal-noise ratio and signal wave has nothing to do only with the signal energy relevant)

BFGS
功能:用BFGS算法求解无约束问题:min f(x)
输入:x0是初始点,fun,gfun分别是目标函数及其梯度;
varargin是输入可变参数变量,简单调用bfgs时可以忽略它,
但是其他程序循环调用时将会发挥重要作用
输出:x,val分别是近似最优点和最优值,k是迭代次数。(Function: BFGS algorithm for unconstrained problem: min f (x) Input: X0 is the initial point, fun, gfun each objective function and its gradient varargin variable parameter is the input variable, it can be ignored when a simple call bfgs , but other programs will play an important role when the cycle is called output: x, val are approximate optimum and the optimal value, k is the number of iterations.)

说明: 观察高斯序列 的时域和幅频特性。
①固定p=8,q分别等于2、4、8,观察它们的时域和幅频特性,了解当q取不同值时,对信号序列的时域和幅频特性的影响
②固定q=8,p分别等于8、13、14,观察p变化对信号序列时域和幅频特性的影响,注意p等于多少时,会发生明显的泄露现象,混叠是否也随之出现?记录实验中观察到得现象,绘出相应的时域序列和幅频特性曲线(Observed Gaussian sequence in time domain and amplitude-frequency characteristics. ① fixed p = 8, q is equal to 2,4,8 respectively, to observe them in time domain and amplitude-frequency characteristics, to understand when the different values of q, the signal sequence in time domain and amplitude-frequency characteristics of ② fixed q = 8 , p is equal to 8,13,14 respectively, to observe the changes in the signal sequence p in time domain and amplitude-frequency characteristics, note that p is equal to the number when the apparent leakage phenomenon, aliasing is also gone? Records of the experiment was observed phenomenon, draw the corresponding time-domain sequence and amplitude-frequency characteristic curves)
