com串口源代码-com string mouth source code

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.

一个对AODV协议流程进行详细说明的文档，对深入学习AODV协议有很好的帮助

PIC18F4550与RFM42无线模块之间的通信；

 该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。     该程序也可以作为学习Matlab 通信仿真的入门实例

一篇详细介绍高速数据调制解调技术，主要以QPSK信号为例，包括解调和定时，挺好的-A detailed introduction of high-speed data modem technology, mainly as an example QPSK signals, including demodulation and timing, very good

SortUtil simple的sort程序。-SortUtil simple procedure of the sort.

一个用VB实现的串口通讯的例子，在按16进制发送的程序中很在参考价值-a VB serial communications, for example by sending the 16-band procedure is the reference value
