本章先分析说明伪谱法求解波动方程的算法原理，再给出弹性波场伪谱法数值模拟的改进算法；然后，通过直接引入P波波场变量和S波波场变量，给出可实现弹性波场的P波和S波分解的波动方程，并用伪谱法实现弹性波场的P波和S波分解的数值模拟；最后用伪谱法对井间地震的复杂波场作数值模拟，分析井间地震波场中各种波的传播规律。(In this chapter, the principle of pseudo-spectral method for solving wave equation is analyzed, and then an improved algorithm for numerical simulation of elastic wave field is given. Then, by directly introducing P-wave field variable and S-wave field variable, the wave equation which can realize P-wave and S-wave decomposition of elastic wave field is given, and the P-wave sum of elastic wave field is realized by pseudo-spectral method. Numerical simulation of S-wave decomposition; finally, pseudo-spectral method is used to simulate the complex cross-well seismic wave field and analyze the propagation law of various waves in cross-well seismic wave field.)

additive_noise_channel
模拟噪声的程序，可以根据需要改写，主要功能是实现噪声模型
(Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details:
op_channel = additivenoise(input_signal)
mathematical Model:
s(t) input signal to channel (=sig_ip)
n(t)additive random noise process added by channel (=noise_mat)
a(t) attenutation factor , here it is taken as random(=att_fact)
out put signal r(t) = a .* s(t)+ n(t)
an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal
