In this paper, resource allocation (RA) problem in heterogeneous Software Defined Network (SDN) with infrastructure sharing platform among multiple network service providers (NSPs) is studied. The considered problem is modeled as a reverse combinatorial auction (R-CA) game, which takes competitiveness and fairness of different NSPs into account. The heterogeneous RA associated with personal QoS requirement...
In this paper, we address the energy-efficient power allocation problem for energy-harvesting device-to- device (EH-D2D) communications, which enable user equipments (UEs) to harvest energy from ambient environments. The challenge is how to optimize energy efficiency (EE) with the intermittent and dynamic characteristics of energy arrivals. We model the offline power allocation problem as a non- cooperative...
Spectrum sensing is one of the most important technique in the cognitive radio. The existing works so far primarily focus on single primary user detection. In this work, we consider cooperative spectrum sensing in cognitive radio networks (CRNs), when there are multiple primary users (PUs) existing. To address the problem of multiple PUs detection, we introduce a novel multi-domain spectrum sensing...
Based on the transfer function, this paper presented a new kind of design method of digital filter in order to eliminate the 50 Hz noise. The filter was realized by software implementation in VC++ environment, and, simulated by Matlab. Experimental results show that algorithm could remove power-line interference effectively, and its operation was simple and applicable.
