    Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

  2. 2. AI Based Methods for Matrix Multiplication in High Resolution Simulations of Radio Access Networks

    University essay from KTH/Matematisk statistik

    Author : Marcus Johnson; Herman Forslund; [2023]
    Keywords : Product-Quantization; MADDNESS; Radio Access Networks; Channel Estimation; MIMO; Approximate Matrix Multiplication; Pruduktkvantisering; MADDNESS; RAN; MIMO; Approximativa matrismultiplikation;

    Abstract : The increasing demand for mobile data has placed significant strain on radio access networks (RANs), leading to a continuous need for increased network capacity. In keeping with that, a significant advancement in modern RANs is the ability to utilize several receivers and transmitters, to allow for beamforming. READ MORE

  3. 3. Mobile Traffic Classification and Multi-Cell Base Station Control for Energy-Efficient 5G Networks

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

    Author : Cai Tianzhang; [2023]
    Keywords : ;

    Abstract : The global energy consumption of mobile networks is rapidly increasing due to the exponential growth of mobile network traffic. The advent of next-generation cellular technologies such as fifth-generation (5G) and beyond promises higher network throughput and lower latency but also demands higher power consumption for its denser base station (BS) deployment and more energy-intensive processors.

  4. 4. Vibration Avoidance Based on Model-Based Control Incorporating Input Shaping

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Chenqi Ma; [2023]
    Keywords : Multi-joint industrial robot; Vibration avoidance; Path deviation; Input shaping; Extended flexible joint model; Nonlinear gray-box identification; Fleraxlade industrirobotar; Vibrationsdämpning; Banavvikelse; Ingångsformning; Utökad flexibel axelmodell; Icke-linjär gray-box modell;

    Abstract : VIBRATION AVOIDANCE, a technique to proactively remove unwanted or excessive vibrations in multi-joint industrial robots, has shown to be desired in various applications. A trade-off between vibration avoidance performance and path deviation has been thekey criteria for assessing the effectiveness and quality of an approach. READ MORE

  5. 5. Cross coupling in a two-axis control system for stabilized platforms

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

    Author : Bill Lavebratt; [2022]
    Keywords : MIMO; Modeling; Two-axis gimbal system; Decoupler; Inner loop disturbance compensation; Control theory.;

    Abstract : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. READ MORE
