数字信号处理和滤波器设计，希望对大家有帮助。(Digital signal processing and filter design, in the hope that everyone has to help.)

其基本思想是：采用信号与噪声的状态空间模型，利用前一时刻地估计值和现时刻的观测值来更新对状态变量的估计，求出现时刻的估计值。它适合于实时处理和计算机运算。 (The basic idea is: use of signal and noise state-space model, the estimated value of the previous time and are always observations to update the estimated state variables, find an estimate of time there. It is suitable for real-time processing and computing.)

采用解调分析方法，从信号中提取调制信息，分析其强度和频次就可以判断研究对象（诸如机械零件）损伤的程度和部位。(Using the demodulation method, the modulation information is extracted from the signal, the strength and frequency analysis can determine the study (such as mechanical parts) and location of the degree of damage.)

本代码可以根据给定的小区数目和小区半径生成网络拓扑结构，并返回基站位置坐标(This code can be based on the given cell number and cell radius generated network topology, and return to the base station coordinates)

HDB3码的MATLAB仿真，可绘出HDB3的波形和功率谱密度。(MATLAB simulation of the HDB3 code, you can draw the the HDB3 waveform and power spectral density.)

实现了用LSB嵌入水印，还有两种水印分析方法：X2和信息量分析法(Achieved using LSB embedding the watermark, there are two kinds of watermarks analysis methods: X2 and the amount of information analysis)
