说明：  16QAM的调制解调程序，用MATLAB实现(16QAM modulation and demodulation of procedures, using MATLAB)

weighted bit flipping algorithm using matlab m-file

说明：  冈萨雷斯（matlab）书中源代码全载。(Gonzalez (matlab) the book contains all the source code.)

同相中相环路，用于符号同步估计。采用simulink设计(PLL for bit/symbol synchronization )

DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同，代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键，10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求： (1) 根据键盘输入的符号，利用MATLAB产生对应的DTMF信号；(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图；(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 (DTMF (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.)

共上载5个源码，其中c语言c_matrix为矩阵类，可以实现几十种矩阵运算；其它四个为matlab程序，用于生各种杂波的程序(Upload a total of 5 source code, in which c language for c_matrix matrices can be achieved dozens of matrix operations the other four for the matlab program for Health and a variety of procedures Clutter)

基天子matlab的双缝干涉从单缝(线光源)发出的单色光射到与之平行的双缝上，即可在双缝屏后获得来自双缝(相干光源)的两束相干光在空间叠加，用光屏承接后可获得干涉图样(在一定范围内出现等间隔明暗相间的平行干涉条纹；用白光做实验则可获得彩色干涉图样)．如果能在计算机上模拟出来.对(Matlab-based emperor s double-slit interference from a single slit (line source) the issue of parallel monochromatic light reach the double-slit can be in the double-slit screen was from the double-slit (coherent light source) of two coherent light beam in the space superimposed with光屏available to undertake after the interference pattern (in a certain range interval appears parallel white light interference fringes experiments using white light interference pattern, they can get color). If we can come out on the computer simulation. On)
