基于VxWorks的FC-IP驱动程序的实现

基于PCI接口的光纤通道主机适配器的工作原理,阐述了该适配器提供的邮箱命令和队列两种软件编程接口工作机制,在此基础上,分析了IP协议在光纤通道上的实现方法,最后在嵌入式VxWorks环境下开发了FC-IP驱动程序,并给出通信性能测试结果。为光纤通道的嵌入式系统中的应用奠定了基础。     

A microwave photonic link with high spurious-free dynamic range based on a parallel structure

A direct detection optical orthogonal frequency division multiplexing(DDO-OFDM)system using turbo codes is built,and the transmission performance comparison between coded system and uncoded system is analyzed.Three decoding algorithms,which are Log-maximum a posteriori(MAP),Max-Log-MAP and threshold Max-Log-MAP,are used in the turbo coded system.By comparing three decoding algorithms,the system using Max-Log-MAP algorithm has the best bit error rate(BER)performance.At the transmission distance of 240 km,the uncoded system with transmission rate of 30 Gbit/s can get the BER performance at the degree of 8.93×10-3 with optical signal to noise ratio(OSNR)of24 d B,while the turbo coded system with transmission rate of 50 Gbit/s can achieve it within OSNR of 20 d B.
