1、将串口通讯协议存储为一个通讯文件，可是随时将存储通讯协议文件调入计算机运行与下位机通讯 可以实现通讯对话，供下位机工程师参考使用，其主要的通讯协议本程序把它们分成四种情况。 以下说明： 1）下位机直接发送数据，上位机只接收不回应数据。 2）下位机直接发送数据，上位机接收并回应数据。 3）上位机直接发送数据，下位机只接收不回应数据。 4）上位机直接发送数据，下位机接收并回应数据。 下位机工程师完全可以利用这个功能单独的并且很方便的调试与上位机通讯程序，更改双方的通讯协议， 不再需要上位机工程师的配合。windwos标准操作，使用方便。 2、可以监听活动串口的数据，将监听到的数据显示到数据显示区里面，可以保存。也可以将原先保存的文件数据读进来，以供分析。数据可以按照Hex和Ascii显示出来。发送所输入的数据，能够定时发送数据，发送文件，提供Hex和Ascii输入方式。 3、可以通过该程序，利用串口将文件发送到另一个计算机上。另一个计算机通过接收文件接收所发出的文件。-1 1 2 3 4 windwos 2HexAsc

In this simulink model , BPSK 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 , BPSK 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.
