这是一个连续相位调制的程序，解调才用的是相干解调，希望对学习有帮助。(This is a continuous phase modulation procedure, before demodulation using a coherent demodulation, and I hope to help learning.)

产生多径衰落信道，有6个可分辨径，每径中有25个径形成瑞利信道。(Generate multi-path fading channel, there are six tracks can be distinguished, each track has 25 tracks form a Rayleigh channel.)

k-mean算法，使用matlab工具箱工具对图像进行聚类分割。(k-mean algorithm, using matlab clustering toolbox tool for image segmentation.)

Phase-shift keying (PSK) is a modulation process whereby the input signal, a binary PCM waveform, shifts the phase of the output waveform to one of a fixed number of states. The demodulation process can be divided into three major subsections, as shown by Figure 4. First, since the incoming waveform is suppressed carrier in nature, coherent detection is required. The methods by which a phase-coherent carrier is derived from the incoming signal are termed, carrier recovery, and will be covered first.

sar图像去噪的几种新的方法，到达过程是的泊松过程，ML法能够很好的估计信号的信噪比。( Several new methods sar image denoising, Arrival process is a Poisson process, ML estimation method can be a good signal to noise ratio.)
