Ternary-Sequence-Based-OFDM-Frame-Synchro-in-WIFI
In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame
synchronization is an essential procedure for normal operation of
the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of
orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation.

三跳协作通信
信道为瑞利信道，S_D的距离为1米，三跳协作通信系统中S_R、R1_R1、S_D的距离均为1/3米。调制方式为BPSK,信噪比在-15dB-15dB间，接收端合并方式为ERC,迭代次数为1000(The channel is Rayleigh channel, the distance of S_D is 1 m, and the distance of S_R, R1, S_D in three-hop cooperative communication system is 1/3 M. The modulation mode is BPSK, the signal-to-noise ratio is between - 15dB and 15dB, the receiver merge mode is ERC, and the number of iterations is 1000.)

vb.RS232
模仿超级终端风格的RS232串口调试工具
这是一个模仿Windows系统带的超级终端风格的RS232串口调试工具。非常容易读取和写入端口，发送支持ASCII字符模式，可以打开二进制文件以16进制格式显示发送。支持工作内容保存，下次加载。
里面的那个动画窗体加载出现蛮有意思，大家可以学习下。尤其对调试AT指令之类的比较方便。(RS232 serial debug tool imitating super terminal style
This is a SuperTerminal style RS232 serial debugging tool that mimics the Windows system. It is easy to read and write ports, send ASCII character mode and open binary files to display in 16 binary format. Support work content to save, next load.
Loading the animated form inside is quite interesting. You can learn from it. In particular, it is more convenient to debug AT instructions.)
