MATLAB 用DFT (FFT)对连续信号进行频谱分析

自己做的CRC16校验例子，输入16进制数据，数据之间用空格，得到校验字节(The CRC16 checksum own example, enter the hexadecimal data, with a space between the data check byte)

it is a very good file for tunable band pass filters

说明：  使用python基于numpy编写函数和程序，完整实现了SC-FDE链路的仿真，包括调制、成型滤波、信道、同步、频偏补偿、均衡、解调。(Full realization of SC-FDE link simulation using python with functions based on numpy.)

枚举所有网卡、获取设置网卡参数、检查网卡状态、启禁网卡(Enum all NICs,get NIC paramates,check NIC state,enable/disable nic)

基于欠采样的超宽带线性调频信号参数估计，硕士论文(Due to sampling-based ultra-wideband LFM signal parameter estimation, master' s thesis)

模仿超级终端风格的RS232串口调试工具 这是一个模仿Windows系统带的超级终端风格的RS232串口调试工具。非常容易读取和写入端口，发送支持ASCII字符模式，可以打开二进制文件以16进制格式显示发送。支持工作内容保存，下次加载。 里面的那个动画窗体加载出现蛮有意思，大家可以学习下。尤其对调试AT指令之类的比较方便。(RS232 serial debug tool imitating super terminal style This is a SuperTerminal style RS232 serial debugging tool that mimics the Windows system. It is easy to read and write ports, send ASCII character mode and open binary files to display in 16 binary format. Support work content to save, next load. Loading the animated form inside is quite interesting. You can learn from it. In particular, it is more convenient to debug AT instructions.)
