运用labview开发环境，实现串口通讯，接受串口发送接收的数据(Development environment using labview, serial communications, sending and receiving serial data received )

说明：  此工程用Visual Studio 2019 编写，目的是用来替换Thorlabs公司自己的GUI Kinesis来控制TDC001伺服电机控制器,方便用户自己控制。(This project is written in Visual Studio 2019. The purpose is to replace the GUI kinesis of thorlabs company to control the tdc001 servo motor controller, which is convenient for users to control by themselves.)

信息经格雷码映射，进行QPSK调制并通过AWGN信道发射，在接收端进行QPSK解调，并统计误符号率和误码率。(Information on the Gray code mapping, QPSK modulation and emission through the AWGN channel, QPSK demodulator at the receiving end, and the statistical symbol error rate and bit error rate.)

在matlab下，基于循环前缀的仿真验证源代码，比较详细(In matlab, the simulation based on cyclic prefix for the source code, more detailed)

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.
