现在通信系统中直扩信号的衰落信道建模的matlab程序(Now Communication System DS signal fading channel modeling matlab program)

最优化算法之一，拟牛顿法，亦称BFGS法，用于求解极值问题，具有二次收敛性(One of the most optimization algorithms, quasi-Newton method, also known as BFGS method for solving extremum problems, with quadratic convergence)

说明：  声波方程正演模拟大模型样例。 包含三个地质层，分别对应速度可以自行修正。 震源函数是雷克子波。 C源程序，输出结果Matlab绘制。(Acoustic wave equation forward modeling big model of the sample. Consists of three geological layers, corresponding to the speed you can correct itself. Lake wavelet source function is. C source code, the output of Matlab draw.)
