PSK信号解调中的定时恢复算法，该算法采用的是早晚门算法，效果较好(Timing recovery algorithm used by PSK demodulator.)

ant colony implementation of recent idea. u can run this on matlab

MSK信号的调制与解调，其中调制采用的是正交调制方式，解调采用的是差分相干解调(MSK modulation and demodulation of the signal, wherein the quadrature modulation using a modulation, demodulation using a differential coherent demodulation)

some fmcw radar matlab source code ,may be useful for the beginner

⑴编程实现直方图均衡化 ⑵设计完成同态滤波器，并用之改善图象质量。 ⑶对某图像加入不同类型﹑不同强度的噪声（周期﹑椒盐噪声），并分别用空间域和频率域的方法抑制噪声。 (⑴ ⑵ programming histogram equalization filter design is completed with the state and used to improve the image quality. ⑶ image of a different intensity with different types of noise ﹑ (cycle ﹑ salt and pepper noise), respectively, with spatial and frequency domain methods of noise suppression.)

集合了很多matlab源代码 能解决matlab图像处理中的很多问题 很好 很强大(Collection of a lot of matlab code matlab image processing can solve many problems very very strong)
