  1. 1. Emergency Power for Wind Turbine Yaw System - Project initialization tool

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Vigan Spahiu; [2020]
    Keywords : Technology and Engineering;

    Abstract : The Yaw Power Backup System (YPBS) is a safety system that needs to be incorporated in the Wind Power Plant (WPP) in order to provide emergency power during a power outage. The YPBS enables the Wind Turbine Generator (WTG) to perform a yawing operation in extreme weather conditions. READ MORE

  3. 2. Pilot Contamination and Mitigation Techniques in Massive MIMO Systems

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

    Author : Vidit Saxena; [2014]
    Keywords : Multicell Systems; Massive MIMO; Pilot Contamination; LTE; Power Control; Resource Allocation; Channel Estimation; Precoding; Technology and Engineering;

    Abstract : A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. READ MORE

  4. 3. Channel estimation in mobile wireless systems

    University essay from KTH/Signalbehandling

    Author : Pazi Alli Idd; [2012]
    Keywords : Time-variant channel; Discrete Prolate Spheroidal Sequences DPSS ;

    Abstract : The demands of multimedia services from mobile user equipment (UE) for achieving high data rate, high capacity and reliable communication in modern mobile wireless systems are continually ever-growing. As a consequence, several technologies, such as the Universal Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project (3GPP), have been used to meet these challenges.

  5. 4. Far-Field Wiener Beamforming and Source Localization in Frequency Domain

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sarath Chandra Uppalapati; Deepak Penugonda; [2012]
    Keywords : Wiener Beamformer; SRP-Phat; SRK-Phat; Reverberation;

    Abstract : In present conference environments where video recording is required, a set of cameras operated by a human being is needed to track the active speaker as he discusses in the conference. In order to automate this procedure, different methods have been developed in acoustic and visual tracking. READ MORE

  6. 5. Synchronization Algorithms and VLSI Implementation for DC-OFDM based UWB System

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)
