说明：  通信系统MATLAB例程 来自MATLAB通信系统仿真(matlab signal communication)

说明：  该软件的处理类似于短时傅立叶变换（STFT），但应用了更长、更重叠的分析/合成窗口，使时频处理从根本上对混叠具有鲁棒性。这种差异与非常活跃的时频处理技术有关，例如Dirac或优化的自适应波束形成器。(The software does processing similar to the short-time Fourier transform , but applies the longer and more overlapping analysis/synthesis window to make the time-frequency processing fundamentally robust for aliasing.)

Labwindows CVI 中不错的串口编程，串口调试(Good serial programming Labwindows CVI, serial debugging )

使用MFC编写的windows环境下的串口操作工程模板(Serial port operation project templates written using MFC windows environment)

说明：  FM（Frequency Modulation）即调频，习惯上用FM来指一般的调频广播（76-108MHz，在中国为87-108MHz、日本为76-90MHz），事实上FM也是一种调制方式，(FM (frequency modulation) refers to the general FM broadcasting (76-108mhz, 87-108mhz in China and 76-90mhz in Japan). In fact, FM is also a modulation mode,)

计算机网络实验做得串口，非原创，只是为了下载方便。(Computer network experiments do serial port, not original, just for download convenience.)

说明：  ns2.33这是目前比较新的ns2版本，欢迎下载(ns2.33 This is relatively new ns2 version, welcome to download)

51MODBUS从机程序源码希望对有用的人有用，，(51MODBUS,welcom to here,thank you very mouch.)

采用GSM系统的GMSK调制方式，并画出出时频域图，计算BER，有利于了解GSM系统的调制解调。(Frequency domain using the GSM system GMSK modulation and draw the diagram, calculate the BER beneficial for GSM modem.)
