802 11a OFDM MATLAB simulation code! (recommended)

GPS接收机将捕获结果按比值形式的直方图输出，Matlab程序(GPS receiver will capture the results histogram output of the Matlab program)

通信基本仿真3,适合初学者学习的代码,包括了调制,分析等等:使用IIR filter的经典模拟滤波器（巴特沃斯Butterworth,切比雪夫Chebyshev）,Bartlett周期图谱，加窗Bartlett周期图谱，基带波形仿真，IIR的贝塞尔滤波器Bessel Filter，二进制对称信道Binary Symmetric Channel仿真，比特序列，Remez滤波，BPSK复合基带信号仿真，载波生成器，椭圆滤波器Elliptical Filter，FFT,FSK调制及解调，高斯噪声Gaussian仿真，直方图，理想AM，线性PLL，BP混淆器，理想MPSK，正交振幅调变（QAM，Quadrature Amplitude Modulation），正交相移键控(QPSK)，Rayleigh Noise瑞利噪声，Yule-Walker Psd功率谱密度函数。(matlab simulte)

关于捷联惯导与多普勒计程仪组合导航的算法程序，比较基础。方便初学者尝试(The algorithm program of SINS and Doppler Log integrated navigation is comparatively basic. Easy for beginners to try)

说明：  在点频信号中加入相噪，可以看到前后对比的可视化信号情况，进行比较(Adding phase noise to point frequency signal.You can see the visual signal before and after comparison and compare.)

说明：  产生正弦信号时域波形及频谱，并通过希尔伯特滤波器。其中希尔伯特滤波器有两种产生方式，一是使用MATLAB自带的FDAtool；二是程序编写。(The time-domain waveform and spectrum of sinusoidal signal are generated and passed through Hilbert filter. There are two ways to generate Hilbert filter, one is to use FDAtool in MATLAB, the other is to write programs.)

坐标转换加上示例坐标文件，代码可结合坐标转换公式进行学习(Coordinate conversion plus sample coordinate file, the code can be combined with coordinate conversion formula for learning)

shape from shaping 3D重构(shape from shaping 3D reconstructed)

DSP语音压缩与回放，开发环境是CCS，实现功能：10秒语音压缩与回放(DSP voice compression and playback, the development environment is the CCS, to achieve functional: 10 seconds voice compression and playback)

光通信中采用OFDM时，信号必须为非负实信号，因此通常采用DCO-OFDM或ACO-OFDM技术，此代码为ACO-OFDM(In VLC the signal has to be real and unipolar. Number of schemes in VLC are proposed in order to provide a real and unipolar signal like U-OFDM , Flip-OFDM , spectrally factorized pptical OFDM].)
