用有限差分模拟高斯脉冲在自由空间传播，运行该脚本，你会得到一个表面，它是由脉冲在1微米的步骤传播。 (Using the finite difference simulation of Gaussian pulse propagation in free space, run the script, you will get a surface, it is spread by the pulse in steps of 1 micron.)

这是EMD分解的matlab程序，可以进行imf分解，及求解包络求解(this is EMD program ，it can process imf divide.)

说明：  该程序实现OFDM系统中块状导频的信道估计，块状导频用于时变较慢的多径信道，可以估计出每个载波上的信道传输情况。(The programme realizes channel estimation with block pilots.)

Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies (integer multiples) of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.

说明：  在同一张图上仿真多幅度电平M电平PAM在M=2,4,8,16时的符号差错概率。(In the same graph simulation multi-level rate of M-level PAM at M = 2,4,8,16 when the symbol error probability.)
