Pilot contamination has become a major capacity bottleneck in massive MIMO systems. To mitigate pilot contamination, a novel cell sectorization-based pilot assignment (CS-PA) scheme is proposed in this paper. By separating the users that transmit the same pilot in physical space, the pilot transmitted by the user in each sector is orthogonal with pilots transmitted by the users in adjacent sectors...
Interferometric synthetic aperture radar (SAR) data offer the opportunity to map the western area of China, acquired from the first Chinese multi-modes airborne SAR mapping system. DEM could be obtained through airborne interferometric pairs. Furthermore, the quality of the InSAR DEM may vary significantly depending on the local topography. Aims of the approach are to smooth the noisy InSAR data,...
Invasive Weed Optimization (IWO) is a recently developed derivative-free metaheuristic algorithm that mimics the robust process of weeds colonization and distribution in an ecosystem. On the other hand central to an ecosystem is the foraging behavior that pertains to the act of searching for food and forms an integral part of the daily life of most of the living creatures. For over past two decades,...
