matlab绘图函数集手册，非常实用。适合于初学者，也适合于有一定基础的matlab用户查阅。(A handbook of set of drawing function in matlab, it is very useful for beginner, also for the users having some basis on usage of matlab.)

代码较长但是很清楚的将伪码-线性调频信号和线性调频信号以及GOLD序列信号的频谱图表示出来并最后得出伪码线性调频信号的模糊函数图(Code is longer but it is clear that the pseudo-code- spectrum chirp chirp signals and signals as well as signals GOLD sequence and came to the conclusion that out pseudo-code chirp signal ambiguity function diagram)

Modulation and demodulation ASK. At the beginning, we create the digital signa (1 and 0), after we do the modulation, add noise and demodulation. At the end we do the reconstruction of the signal.
