We propose a rectangular optical filter based on stimulated Brillouin scattering in fiber with tunable bandwidth from 50 MHz to 4 GHz at 1.-MHz tuning *** steep-edged rectangular shape of the filter is precisely controlled utilizing digital feedback revision of the pump *** passband ripple is~1.dB by nonlinearity management of the pump and using the fiber with a single Brillouin *** extinction ratio of the filter is further enhanced using the polarization characteristics of the Brillouin *** on this filter,we demonstrate a sub-band extraction of a multi-band orthogonal frequency division multiplexing signal,which shows the potential ability of the filter in the fields of optical and microwave signal processing.

To handle the handover challenge in Express Train Access networks(ETAN).mobility fading effects in high speed railway environments should be addressed *** on the investigation of fading effects in this paper,we obtain two theoretical bounds:HOTiming upper bound and HO-Margin lower bound,which are helpful guidelines to study the handover challenge today and in the ***,we apply them to analyze performance of conventional handover technologies and our proposal in *** follow-up theory analyses and simulation experiment results demonstrate that the proposed handover solution can minimize handover time up to 4ms(which is the fastest one so far),and reduce HO-Margin to 0.1. dB at a train speed of 350km/h.

In optical satellite network, the possible optical inter-satellite links (OISLs) candidate for each satellite are usually more than laser communication terminals (LCTs) equipped. This poses the link assignment problem (LAP) of how to assign LCTs of each satellite to establish OISLs with the others. In order to make full use of huge bandwidth provided by LCT, the problem of assigning all satellite LCTs to establish OISLs is modeled as a perfect matching problem in the perfect match model, where a perfect matching is searched over a mixed complete bipartite graph. The regular, random greedy and perfect match model based link assignment schemes are considered. Simulation results show that the average node-to-node distance and LCT utilization of perfect match model based link assignment scheme are better than the regular and random greedy link assignment schemes.
