软判决在OQPSK解调中实现对信号纠错的分析与应用(Soft-decision in OQPSK achieve signal demodulation analysis and application of error-correcting)

Matlab的一些应用程序例子，可以供大家参考下，谢谢大家的支持(Matlab some application examples, for your reference, thank you for the support )

this is a matlab code for h.264 coding

光通过三菱镜动态仿真，matlab程序，学习光学仿真必看的代码(Mitsubishi mirror light through dynamic simulation, matlab program, learning the optical simulation must-see code)

FFT频率提取的MATLAB实现，有具体的图形(FFT frequency extracted MATLAB realize, there are specific graphics)

说明：  均值平移跟踪算法中核函数窗宽的自动选取代码，根据目标大小变化核窗宽，使得当目标出现大小变化时准确跟踪到目标中心(The automatic selection code of kernel function window width in mean-shift tracking algorithm changes the kernel window width according to the size of the target, so that the target can be accurately tracked to the target center when the size of the target changes)

EXIT图，外信息转移图，对做迭代分析的非常有帮助。(EXIT chart, extrinsic information transfer chart, right to do iterative analysis very helpful.)

有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。(There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.)
