MINIMIZATION OF FEEDBACK LOOP DISTORTIONS IN DIGITAL PREDISTORTION OF A RADIO-OVER-FIBER SYSTEM WITH OPTIMIZATION ALGORITHMS

Minimization of Feedback Loop Distortions in Digital Predistortion of a Radio-Over-Fiber System With Optimization Algorithms

This article proposes the linearization of an intensity modulation/direct detection radio-over-fiber (RoF) link with feedback loop.The goal is to carry out the predistortion process in a real scenario, in which the output signals are a few kilometers far from the baseband unit (BBU).First, the MOISTURIZING MASK feedback loop is considered ideal, so

A geometric misregistration resistant data fusion approach for adding red-edge (RE) and short-wave infrared (SWIR) bands to high spatial resolution imagery

High spatial resolution images have been widely applied to the monitoring of land surfaces during the past decades.However, satellite and unmanned aerial vehicle Feet (UAV) sensors (e.g., IKONOS, and QuickBird) usually only provide visible and near-infrared spectral bands with a high spatial resolution.Such limited spectral bands at a high spatial
