LTE系统中同步和信道估计的FPGA设计与实现_刘凯

说明：  关于多块板子利用485总线 采用MODBUS协议实现开关量采集与控制采集，串口打印。(On the use of 485 bus and MODBUS protocol to realize switch data acquisition and control acquisition, serial port printing.)

说明：  介绍DSP与上微机的串口通信和功能设置，及通信调试(introduced DSP and PC on the serial communications and functionality, and communication Debugging)

串口调试工具c#源码，波形显示上位机，可以显示实时波形(serial port)

ofdm系统模型,包含信道估计 FFT变换 QPSK 16QAM调制 插入导频等,非常全面,(The ofdm system model, including channel estimation, FFT transform, QPSK 16QAM modulation, insertion pilot, etc., is very comprehensive.)

实现串口通信功能。由中断程序调用，实现串口单字节读写的功能。(Realize the serial communication function. By the interruption of the procedure call, the realization of single-byte read and write serial port function.)

基于F28335的SCI串口通信程序。本程序的特点是代码简单、高效。本代码共包含三个工程文件：1、基本通信（实现了最基本的通过SCI协议通讯的功能。上位机下发一个字符或字符串，下位机原样返回该字符或字符串）；2、SCI通信FIFO版（在1的基础之上启用了FIFO缓存接收或发送的数据）；3、SCI通信FIFO与中断版（通过启用FIFO功能减少对CPU资源的占用，且数据的发送与接收处理均在中断中完成）。此三个程序基本验证了F28335的SCI模块所有功能。(F28335 of SCI-based serial communication program. Features of this program is the code simple and efficient. This code contains a total of three project files: 1, the basic communication (via SCI achieve the most basic functions of communication protocols issued the PC or a character string as the next crew to return to the character or string.) 2, SCI communication FIFO version (on the basis of a FIFO buffer above the receive or transmit data enabled) 3, SCI communication FIFO and interrupt version (FIFO function by enabling reduce the occupancy of CPU resources, and sending and receiving data are processed in interrupt completed). The three basic procedures to verify the F28335 all functions of SCI module.)

matlab实现串口通信，心电信号实时显示，QRS波提取(matlab serial communications, real-time display ECG, QRS wave extraction)

This is the source code for I2C(Inter Integreted Circuit) which is used in serial communication

Wincc使用MSComm控件串口通讯，VB中发送十六进制数据(Wincc uses MSComm control to communicate through serial port and sends hexadecimal data in VB)

串口拍照源程序,通过串口得到摄像头部分的JPEG数据,再把数据还原成JPG图像(Serial camera source, camera part of the JPEG data through the serial port, and then restore the data into a JPG image)
