开放源码的smpp协议开发包，最新版本0.3.6，有详细文档及示例。...

应用背景应用于通信系统信号的调制解调实例，通过systemview软件搭建通信系统仿真平台，给出了信号的调制解调过程及波形具体形式，为与通信实际环境相关，采用高斯噪声模拟通信信道。关键技术SystemView主要用于搭建通信系统平台，采用了软件中的相关器件实现信号的调制及发射。采用低通滤波等得到基带信号，然后采用单刀双掷开关等器件完成判决，实现解码。

串口控件编程，使用mscomm控件，串口控件有别于文件流方法，易学易懂，但是必须安装这个控件。-Serial control programming, using mscomm control, serial control is different from the file stream method, easy to learn and easy to understand, but must install the controls.

In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
