Based on the Matlab/Simulink simulation models, This research focused on the application of Pontryagin's Minimum Principle in the energy management design of plug-in hybrid electric bus. This paper offers brief introduction of Minimum Principle, definition of specific problem, realization of this principle in Matlab environment and the final comparison of the fuel cost among Minimum Principle-based...
This paper considers the p-Cycle network protection technique in comparison with the ring cover technique for elastic optical networks. We develop an Integer Linear Programming (ILP) model to minimize required protection capacity and used link spectra in the entire network. We also apply the Bandwidth Squeezed Restoration (BSR) technique to obtain the maximum restoration levels for the affected service...
A macrocell superposed by indoor deployed femto-cells forms a geography-overlapped and spectrum-shared two-tier network, which can efficiently improve coverage and enhance system capacity. To reduce inter-tier co-channel interference, femtocell user should choose suitable access channel according to the path losses between itself and the macrocell users. Path loss should be estimated non-cooperatively...
Femtocells deployed in the Macrocell to improve the indoor coverage share the same spectrum with the Macrocells. The dynamic spectrum access (DSA) and power allocation (PA) for the users of Femtocells and Macrocells has an important influence on the mutual interference and system performance in Femtocell networks. In this paper, the DSA and PA problem is first modeled as an optimization problem. Then,...
Ambiguity function method is used to study the ranging and Doppler tolerance performance of CW signal based on pseudo-random code bi-phase modulation (PRCBPM). Its ranging resolution and Doppler tolerance confine are calculated, the ranging performance and Doppler tolerance capability are simulated by using the software of Matlab and the influence factors are analyzed. The simulation results are consistent...
