这是一个在matlab下模拟ask 和 bpsk调制和解调的代码-this is a file wirtten by Matlab, to explain the ASK and BPSK in a correctly way

线调频小波源程序，通过线调频小波可以有效地估计出信号在时频分析中的转频，Chirplet小波可以看成是STFT和小波变换的推广，Chirplet小波结合了STFT变换和小波变换优点，比较好处理了频率与时间的关系

说明：  双音频按键识别 背景： 打电话拨号时，每次按键会发出不同的声音，这些声音实际上是由一些固定频率的正弦信号合成的。因为每个按键声音包含两个不同频率的正弦信号，因此也被称为“双音频”信号，简记为DTMF。这相当于是对不同键位用‘音频’进行了编码，如同计算机领域中用数字0和1对处理对象（包括键盘）进行编码。(Two-tone buttons identify Background: When you call dial, each key emits different sounds, which is actually made up of some fixed frequency sinusoidal signal synthesis. Because the sound of each key contains two sinusoidal signals of different frequencies, it is also known as &quot two-tone&quot signal, abbreviated as DTMF. This is equivalent to different keys using the ' audio' encoded, as the computer industry with the numbers 0 and 1 pair of processing object (including the keyboard) to be encoded.)

此程序能在MATLAB上实现低通滤波器，功能很强大(That this procedure can in MATLAB to achieve low-pass filter, a very powerful feature)

本资料为杨鹏老师所编，内涵了gre词汇的背诵方法，以及以前版本所没有的易混单词，实为难得的好材料(the book mainly describes an effective way to recite GRE words.)
