  1. 16. Optical communication with underwater snake robots : Design and implementation of an underwater wireless optical communication system

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Jaime Marco Rider; [2019]
    Keywords : optical communications; underwater wireless; robot communications;

    Abstract : Eelume AS is a norwegian company that develops autonomous underwater vehicles. Their flagship model is an underwater snake robot that performs inspection, maintenance and repair operations. For the time being, Eelume has been using acoustic communications between their AUV's and the docking station, but it has a big drawback: bandwidth. READ MORE

  5. 19. Hardware-Efficient WDM/SDM Network : Smart Resource Allocation with SDN Controller

    University essay from KTH/Kommunikationssystem, CoS

    Author : Lida Liu; [2019]
    Keywords : WDM; SDM; SDN; routing and wavelength assignment; large-scale network; hardware resource; WDM; SDM; SDN; routing och tilldelning av våglängd; storskaligt nätverk; hårdvara resurs;

    Abstract : Optical networking has been developing for decades and wavelength-division multiplexing (WDM) is the main technology used to carry signals in fiber-optical communication systems. However, its development has slowed because it is approaching the Shannon limit of nonlinear fiber transmission. READ MORE

  6. 20. Implementation of High-Speed 512-Tap FIR Filters for Chromatic Dispersion Compensation

    University essay from Linköpings universitet/Datorteknik

    Author : Cheolyong Bae; Madhur Gokhale; [2018]
    Keywords : DSP; VHDL; FIR; Digital communication; Optical networks; Chromatic dispersion;

    Abstract : A digital filter is a system or a device that modifies a signal. This is an essential feature in digital communication. Using optical fibers in the communication has various advantages like higher bandwidth and distance capability over copper wires. READ MORE
