一个matlab小程序，三次输错密码后，可以调用摄像头进行拍照，并发送飞信和电子邮件（当然需要进行必要的设置，注释很清楚）(A small matlab program, three times the wrong password, you can call the camera to take pictures and send flying letters and e-mail (of course, need to take the set, comments very clear))

Obtain the CDF plots of PAPR from an OFDM BPSK transmission specified per IEEE 802.11a specification Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely. Using a small script, the cumulative distribution of PAPR from each OFDM symbol, modulated by a random BPSK signal is obtained
