In this simulink model , QPSK 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 , QPSK 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.

嗨伙计们，这是我第一篇文章，下面是在 C# 中使用串口的基本项目的描述。我创建一个程序，使用写入和读取。与 Texbox 你写任何你想要和点击"发送"，此消息是通过串行通讯 （RS232、 RS485、 RS422，TTL） 发送。每一次，timer1 的事件处于活动状态，将调用 portSerial，并将文本框 （form1 中） 中显示的消息。
