The PAPR of QAM system is plotted against Complementary cumulative distribution function

包括灰色模型主程序灰色模型被调用子函数，该子函数命名为(Including gray model is called the gray model main subroutine, the subroutine named)

papr to differenrt number of subcarrier: we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation. The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high PAPR induces a high dynamic range which describes high variability in the signal range. complex data sequences are input to the IDFT of an OFDM transmitter then at the output of the IDFT, real and imaginary parts are obtained.

MATLAB相关的PPT 很齐全，讲解由浅入深，是初学者学习很好的资料。(MATLAB related PPT is complete, on the easy-to-digest, is very good information for beginners to learn.)

压缩传感L1范数译码源程序，程序简单易懂注释详细，对初学者有很大帮助(L1 norm compressed sensing decoding source code, the program easy to understand comments detailed, very helpful for beginners)

说明：  在matlab7中可以运行。其功能是实现用CV模型对灰色图像进行分割。(It Can be run in matlab7. function: It can make the gray image segmentation using the CV model .)
