Mathematica函数 函数使用介绍和软件使用介绍(Mathematica function function description using the description and software)

2opt metaheuristic algorithm greedy

DSP各款芯片的原理图和PCB图，不错的学习资料(DSP sections of the chip and the PCB schematic diagram, a good learning materials)

粒子群算法的局部模型程序，比全局模型的效果要好，尽管收敛速度慢些，但是都能找到最优点。(PSO partial model program than the overall model is better effect, despite the convergence speed more slowly, But can find the most advantages.)

DS_CDMA的程序实现 主要分为同步和异步的程序代码，可以自己进行仿真(The program realization are divided into synchronous and asynchronous DS CDMA program code, can simulate ourselves )

this is basic matlab explanation. i will upload 5documents.

说明：  数字波束形成技术的应用 适合于毕业设计 是将来的前沿技术(Digital beam)

In this letter, we propose anovel family of windowing technique to compute mel frequency cepstral coefficient (MFCC) for automatic speaker recognition from speech. The proposed method is based on fundamental property of discrete time Fourier transform (DTFT) related to differentiation in frequency domain. Classical windowing scheme such as Hamming window
