摘要
针对某型作战指挥系统中通信网络的传输信号多样性和复杂性,以及信道利用率低的现状,提出了以1310nm/1550nm光纤作为传输媒介,基于FPGA的多路、多速率模拟/数字信息综合传输的设计方案;采用了多种复用技术将不同种类的信号进行处理,复用到单根光纤上传输,以QuartusII4.0为编译环境,以VHDL语言为开发工具实现了CMI和HDB3编译码;实验结果表明:系统语音信号清晰,数字信号传输误码率低,工作性能稳定;这说明基于FPGA的多路数据光纤传输系统设计是成功的。
For a certain type of combat command system, the signals of communication network were multiformity and complexity, which showed Channel status of low utilization. A new design was proposed as integrated Transmission system based on FPGA and a transmission medium of 1310nm/1550nm optical fiber, based on multi--channel and multi--speed analog / digital information. Using a variety of multiplexing technology to process different types of signals into one signal to transmit on the optical fiber, the design of optical fiber transmission code with a QuartusⅡ 4.0 envi- ronment and VHDL tools in order that CMI and HDB3 were coded. The results showed that; voice signal could be transmitted clearly , meanwhile digital signal transmission had little wrong code rate and stable performance, which has great practical value.
