Fourier Spectra for Face Recognition

说明：  在扩频系统中对加入的不同噪声进行仿真的源代码(in spread spectrum systems to join the different simulation of noise source)

基于AM DSB SSB调制解调的程序，较好的组织了语言描写，展示了通信系统中最基本的调制解调过程知识(Based the AM DSB SSB modulation demodulation process, preferably organized language description, showing a basic knowledge of the modulation and demodulation process in the communication system)

用快速傅立葉轉換來求出訊號頻譜的練習過程，並舉一個實例:用FFT來算方形孔徑的遠場繞射(Exercises of the signal spectrum is obtained using a fast Fourier transform FFT to count the the square aperture far-field diffraction)

相关器可以主要对不同的信号做相关检测，可以用于信号的提取，以及时间延迟的计算(Correlator can be mainly related to do different signal detection, can be used for signal extraction, as well as the time delay calculation)

matlab是集数学计算、图形处理和程序语言设计于一体的软件，通过matlab来实现数字信号处理的有关表达，最终实现课程设计的目的。(matlab is a mathematical calculation, graphics processing and programming language design software integrated through matlab to realize the digital signal processing of expression, and ultimately realize the purpose of curriculum design.)

说明：  lms算法的仿真和yule_walker方程的仿真。这两种算法都是随机信号处理的有效方法。(lms algorithm yule_walker of the simulation and the simulation equations. These two algorithms are effective random signal processing methods.)

我自己写的OFDM的一些仿真程序，时域图、频域图以及一些错误图样等。(I wrote it myself a number of OFDM simulation program, time-domain diagrams, frequency-domain maps and drawings and so some errors.)
