Abstract In order to reduce the risk of authorized users being interrupted in cognitive satellite wireless network, a multi-step prediction approach based on cascaded forward artificial neural network is proposed predict user behavior designed scenario. This uses powerful learning ability analyze historical spectrum occupancy records licensed users, and then next few time slots. The result can help base station schedule dynamic access process interference caused by users. Finally, compared...
In this paper, we mainly research on the QoS (Quality of Service) routing algorithms for MEO/LEO (medium Earth orbit/low orbit) double-layered satellite networks. type networks, rapidly changing network topology due to relative motion satellites is one main challenges when designing an efficient algorithm. Specifically, issues high rerouting overhead and traffic with diverse requirements remain be resolved. This paper proposed a M-BMDP (modified bandwidth constrained minimum delay path)...
Given that single-state model can just describe single channel environment, and multiple-state brings more parameters complicated simulation work, then a three-state Markov statistical modeling of dual-polarized MIMO-LMS channels with satellite is proposed. And these three states are separately LOS (line-of-sight) state, intermediate shadow state deep state. Based on the proposed model, through detailed computer simulations, time series capacity for $4\times 2$ $2\times in open rural...
The integrated satellite and terrestrial network has become one of the frontier technologies next generation mobile communication system. is used as an extension supplement ground to achieve seamless coverage wireless communications. spectrum sharing realized from perspective planning, considering number co-frequency terminals distance between terminal center beam. existing schemes use concept geographic isolation, which will limit available bandwidth network. Therefore, time domain...
