  1. 1. Triggningskriterier i triggningsmodul för trådlösa dataloggern DL141E

    Kandidat-uppsats, Högskolan Kristianstad/Avdelningen för datavetenskap

    Författare :Aleksandar Jovanovic; Cong Vu; [2018]
    Nyckelord :Data logger DL141E; signal processing; ramp; pulse; software triggering criterias; pre-samples; Lebesgue sampling; send on delta; Dataloggern DL141E; signalbehandling; ramp; puls; mjukvarumässiga triggningskriterier; försampel; Lebesgue sampling; send on delta;

    Sammanfattning : Dataloggern DL141E möjliggör kontinuerlig loggnig av mätdata från sensorer på upp till 30k sampel/s, som vidare kan överföras till mobiltelefoner via trådlös kommunikation. Detta är dock för stora datamängder per tidsenhet för mobiltelefoner som är tekniskt begränsade. LÄS MER

  3. 2. Block Diagonalization Based Beamforming

    Master-uppsats, KTH/Teknisk informationsvetenskap

    Författare :Darshan Patil; [2017]
    Nyckelord :;

    Sammanfattning : With increasing mobile penetration multi-user multi-antenna wireless communication systems are needed. This is to ensure higher per-user data rates along with higher system capacities by exploiting the excess degree of freedom due to additional antennas at the receiver with spatial multiplexing.

  4. 3. Silicon photonics based MEMS tunable polarization rotator for optical communications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sandipan Das; [2016]
    Nyckelord :Silicon photonics; MEMS; Tunable polarization rotator; Polarization beam splitter; Kiselfotonik; MEMS; Flytande polarisationsrotator; polarisationsstr°aldelare;

    Sammanfattning : There has been a huge surge in data traffic all over the world due to the rise of streamingmedia services and connected devices. The current demand in data traffic has alreadypushed the optical fiber in the internet architecture to the network edges and the trend isto push it as close as possible, to the CPU. LÄS MER

  5. 4. Development and Evaluation of UTDoAas a Positioning Method in LTE

    Master-uppsats, KTH/Signalbehandling

    Författare :Thomas Arthur Herbert Bressner; [2015]
    Nyckelord :LTE; TDoA; TDOA; Positioning; UTDoA; UTDOA; Thomas Bressner; Bressner;

    Sammanfattning : Although positioning has been one of the main target study areas in mobile communication in the last decade, it still receives strong attention in recent years focusing more on the indoor users. Nowadays, a wide range of different methods are available to estimate the position of the target user under certain circumstances. LÄS MER

  7. 5. GOVERNOR ELECTRONICS FOR DIESEL ENGINES : High availability platform for real-time control and advanced fuel efficiency algorithms

    Master-uppsats, Akademin för innovation, design och teknik

    Författare :Johnny Holmström; [2013]
    Nyckelord :diesel-governor; signal-conditioning; electronics; FPGA; marine-vessels; varvtals-regulator; signalbehandling; elektronik; FPGA; sjöfart;

    Sammanfattning : Fossil fuel is a rare commodity and the combustion of this fuel results in negative environmental effects. This paper evaluates and validates the electronics needed to run intelligent algorithms to lower the fuel consumption for commercial vessels. LÄS MER
