从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

正交频分复用（OFDM）的调制与解调以及OFDM的误码率。(Orthogonal Frequency Division Multiplexing (OFDM) modulation and OFDM demodulation and bit error rate.)

用来演示太阳、地球、月亮、卫星同时绕转的动画，体现他们之间的关系(Used to demonstrate the sun, the earth, the moon, orbiting satellites simultaneously animation, reflecting the relationship between them)

Matlab code for OFDM transmission simulation.

这里是通信领域中各种基带信号（非常全，几乎最新的都有），用matlab编写，给出了相应的带宽和功率谱密度，很值得学习通信的看看(Here are the various communications baseband signal (very full, almost all the latest), written with matlab, the corresponding bandwidth and power spectral density, it is worth learning to see communication)

this is useful to generate noise in communication channels at the time of simulation
