  1. 11. Physical Layer Algorithms for Intrabody Nano-Communications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anders Enqvist; [2018]
    Keywords : ;

    Abstract : In this thesis we develop a mathematical model of the physical layerfor an in-body nano-machine (NM) communication. The purpose isfinding what modulation and detection schemes are suitable for applicationin the body and discovering what factors limit the feasiblecommunication distance. READ MORE

  3. 12. Frequency Tracking Using Digital Cavities

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Fredrik Zetterblom; [2017]
    Keywords : Digital cavities; Frequency Tracking; Technology and Engineering;

    Abstract : Digital cavities are efficient algorithms for comb filters with very low computational costs. They have been used to precisely measure the amplitude and phase of high frequency signals (few giga samples per second) from data acquired by high speed digitizers 80 GSps. READ MORE

  4. 13. Modulation schemes in ambient backscatter communication

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Oliver Harms; [2017]
    Keywords : ;

    Abstract : This thesis presents a study of different modulation schemes in the context of backscatter communication. Backscatter communication is a way of wireless communication where no active signal is transmitted. Instead surrounding signals are modified to transmit data. READ MORE

  5. 14. Intradyne Signal Recovery and Equalization for Optical Satellite Links

    University essay from KTH/Rymd- och plasmafysik

    Author : Philip Conroy; [2017]
    Keywords : ;

    Abstract : An optical communication system employing intradyne reception withoffline digital signal processing for a geostationary satellite communicationscenario is presented. The digital signal processing is improvedvia the implementation and comparison of several timing recovery algorithms,and the inclusion of an equalization stage. READ MORE
