1. 6. Study and Measurement of Scatter Effect on Wireless Channel using Realtime LTE Co-Operative Relays

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Sammanfattning : Relays are an important application of the fixed wireless access channel (FWA), with fast growing needs for higher throughput cooperative schemes are standardized to enhance throughput and cooperative relays are a realization of the standard. We study the effects of moving scatters on the FWA channel with simulation and real-time LTE measurements with testbed and characterize the FWA MIMO channel based on its performance and small scale movements in the environment, compare the LOS and NLOS effects of channel in relation to scatter movements and antenna height.

   Sammanfattning : The objective of this work was to study the addition of fluorescent whitening agents (FWAs) for efficient use on pigment coating of paper substrates with low grammage and the goal was to achieve high optical response by using low amount of FWAs. A commercial light-weight coated (LWC) paper grade was provided by Stora Enso Corbehem Mill and isotropic laboratory sheets were produced at Stora Enso Research Centre using PFI sheet former. LÄS MER
