使用一组陀螺实测数据为原始数据，通过时变卡尔曼滤波，得到两组输出滤波图(Use a gyroscope data as raw data, through the time-varying Kalman filtering, the final two output filter figures are obtained)

UWB，超宽带信号分析必用的子函数，第14部分！(UWB, ultra-wideband signal analysis will be used for Functions, Part 14!)

说明：  测试ADC输出的SNR，将ADC输出数字信号变换为模拟信号求SNR(pipelined ADC SNR)

中值滤波算法去除椒盐噪声，小生亲自编写的(voice pepper removal algorithm was removed during the wave)

所谓跳频，比较确切的意思是：用一定码序列进行选择的多频率频移键控。(The so-called frequency hopping, the exact meaning is: a certain code sequence selected frequency to frequency shift keying.)

This program is about short time fourier transform.

应用于扩频通信，关于PN码扩频，在matlab中的完整程序代码。(Applied to spread spectrum communication, spread spectrum on the PN code in matlab full program code.)

：以系统仿真软件MATLAB中的Sin-mlink软件包为工具，完成了通信系统中超外差接收机的动态仿真，并得到了完整的 仿真结果，总结出了利用Sitmdink进行动态仿真的基本方法和步骤。(: A system simulation software in the MATLAB software package for the Sin-mlink tools, completed a communication system in the dynamic simulation superheterodyne receiver, and a complete simulation results, summed up the use of dynamic simulation Sitmdink basic methods and steps.)

说明：  matlab实现模拟退火,程序实现很有效果(matlab implementation of simulated annealing, the program to achieve very effective)

DS的信号调制解调，是基于matlab的的M文件。(DS signal modulation and demodulation, is based on the M-file matlab.)
