无线激光通信协议的设计(英文)

Protocol design for free space optical communication

研究了无线激光通信(FSO)与传统激光通信的区别,编制了一套FSO物理层收发协议。采用现场可编程门阵列(FPGA)完成收发机与外部电路的数据通信,利用先入先出(FIFO)存储器完成收发协议与外部系统的接口。设计的物理层收发协议主要完成发送数据的编码、串行化以及接收数据的解串行化和解码。仿真实验结果表明:设计的收发协议可实现在40 Mbps通信速率下的稳定工作,证明了该收发协议设计的可行性。

The differences between Free Space Optical（FSO） communication and traditional communications are investigated,and a physical layer transceiving protocol is built.A field Programmable Gate Array（FPGA）is introduced to achieve the data communication of both the transceiver and outer circuits,and a First in First out（FIFO） memory is utilized to implement the interface of protocol and outer systems.The protocol mainly achieves coding and serializing of the transmitting data and deserializing and decoding of the received data.The result of simulation experiment proves that the transceiving protocol is feasible,which can work reliably at a speed of 40 Mbps.
