  1. 1. Beam-steered Modulation in Advanced Antenna System

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

    Author : Smitha Jinnahalli Venugopal; [2023]
    Keywords : 5G-MIMO; Beam-forming; Beam-steering; Advanced antenna systems; Technology and Engineering;

    Abstract : The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. READ MORE

  3. 2. Resilient routing and spectrum assignment in Elastic Optical Networks under Dynamic Traffic

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

    Author : Christian Thiessen; [2014]
    Keywords : ;

    Abstract : Transparent Elastic Optical Networks (EON) are seen as a promising solution for future optical transport networks to keep up with internet traffic growth, as they allow provisioning connections with different bandwidth requirements in an efficient way. To achieve high spectrum efficiency in these networks, making good Routing, Modulation and Spectrum Assignment (RMLSA) decisions is essential. READ MORE

  4. 3. Dynamic load modulation

    Author : Björn Almgren; [2007]
    Keywords : load modulation; load tracking; power added efficiency; high efficiency; PA; power amplifier; switch mode; switching; dlm; lm; et; envelope tracking; modulation; load; efficiency; PAE;

    Abstract : The purpose of this master thesis was to study if the drain efficiency of power amplifiers can be maintained at power back off using a technique called load modulation. The amplifier classes studied are E, F and D-1. The target figure was to obtain a 10 to 12 dB dynamic range of amplitude with reasonable efficiency. READ MORE
