Frequency-Shifting Properties of DTFT

Beyond software architecture

Barlette 方法估算入射信号源的到达角的方法，使用Matlab工具。(a simple and good Barlette method for doa estimation.)

运用matlab进行ls与dft对比，从而得到二者不同(Ls using matlab for comparison with dft, resulting in two different)

椭圆算法，可用Matlab编程,也可用Mathematica软件编程，给出的是Mathematica程序(Ellipse algorithm, the available Matlab programming, can also be used Mathematica software programming, given the Mathematica program)

计算成组滑动的滑窗检测器的最佳门限已知: 击中数N = 128, 组宽n = 8，PF = 10¡ 6，PD = 90 假设以下条件: (a) 信号不起伏 (b) 忽略天线波束调制 1 (c) 计算PD时忽略目标区以外噪声的影响 组门限(第二门限)为K=8 滑窗的门限(第三门限)为L=16 (滑窗中包含的组数为16) 求解: 最佳的KOPT 和LOPT，对这题做了具体仿真实现。需要的朋友，一定知道很有用。(Optimal threshold calculated as group slidable window detector is known: hit number N = 128, the group width n = 8, PF = 106, PD = 90 assuming the following conditions: (a) signal is not undulation ( b) ignore the antenna beam modulation 1 (c) the calculation of PD ignored outside the target area noise of impact group door limit (the second door limit) for K = 8 sliding window of the door limit (third door limit) for L = 16 (sliding window contains group 16) to solve: the best of the KOPT the LOPT, these questions do specific simulation to achieve. A friend in need, we must know to be useful.)
