本文在确定了水声信道的数学描述后,提出了在信道自适应过程中,可以应用 子波对信号进行多分辨率分解,逐尺度地对信道进行均衡. 这样,不但减少了运算数 据量,也减少了均衡所需的权系数个数.(equalizer)

说明：  卡尔曼滤波器是用前一个估计值和最近一个观察数据估计信号的值，他是用状态方程和递推的方法进行估计，本例用来追踪一个5阶的FIR不确定的滤波器系数。(Kalman filter is to use the previous estimate and the most recent observation data to estimate the value of the signal, he is using the state equation and recursive estimation methods, in this case is used to track a 5-order FIR filter coefficients of uncertainty.)

穿墙传播带来的误差分析例程，对于非视距的认识可以加深(error analysis about through-wall propagation)

这是《wcdma无线网络规划与优化》书上对应的源代码的第二部分，共有10个matlab源程序代码。("wcdma wireless network planning and optimization" book on the source code corresponding to the second part, A total of 10 Matlab source code.)

说明：  有限差分声波波动方程正演。主要用于地震勘探正演(Finite difference method of acoustic wave equation forward modeling)

针对水声中的矢量圆阵，比较MUSIC算法与MVDR算法的分辨率和抗各向同性噪声的能力。(For underwater acoustic vector in circular array, the MUSIC algorithm with the ability to compare MVDR algorithm isotropic resolution and anti-noise.)

混沌模糊算法函数，调用此函数可以解决许多初学者的疑惑(Chaotic fuzzy arithmetic functions, calling this function can solve many doubts beginners)

说明：  加信噪声，单边带调幅，设计波特滤波器，过滤噪声，比较经过希尔伯特变换前后的区别(Plus letter noise, single-sideband amplitude modulation design Potter filters, filter noise comparison, after the difference between before and after the Hilbert transform)
