We propose a rectangular optical filter based on stimulated Brillouin scattering in fiber with tunable bandwidth from 50 MHz to 4 GHz at 15-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.

An auction-based joint subcarrier and power allocation approach is investigated to improve the performance of device-to-device (D2D) communication underlay cellular networks with uplink (UL) resource sharing. To maximize the system sum rate over the resource reuse of multiple D2D pairs, we introduce a reverse iterative combinatorial auction to formulate the optimization problem. In the auction, cellular channels are viewed as bidders competing to obtain rate increase while packages of D2D pairs and the corresponding transmit power are auctioned as goods in each round. We first give the evaluation of bidders' optimal value for packages, and then explain a descending price auction in detail, also give properties of convergency and low-complexity. The simulation results are finally provided to indicate the efficiency of the proposed auction-based algorithm.

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.
