    Sammanfattning : With the tremendous growth in the mobile data traffic, the demand for highdata rate is increasing rapidly, and higher frequency resources shall be exploredto alleviate the congestion in the overcrowded spectrum, thus, the millimeterwave (mmWave) frequency resource ranging from 30 GHz to 300 GHz has beenrecognized as a nature fit for the fifth-generation (5G) and beyond network. Tocompensate the severe path-loss in the mmWave band as well to realize theefficient transmissions by applying the low-cost architecture, it is of intereststo investigate the beamforming schemes with large-scale antenna arrays andthe full-duplex (FD) relaying strategy, which are indispensable in the operationof directional signal transmission and the efficient spectrum utilization inthe mmWave transmission, respectively.

    Sammanfattning : It is often desirable to find the underlying trends in time series data. This is a wellknown signal processing problem that has many applications in areas such as financial dataanalysis, climatology, biological and medical sciences etc. LÄS MER

  4. 3. Using ADMM for Hybrid System MPC

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Mattias Fält; Lucas Jimbergsson; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Model Predictive control (MPC) has been studied extensively because of its ability to handle constraints and its great properties in terms of stability and performance [Mayne et al., 2000]. We have in this thesis focused on MPC of Hybrid Systems, i.e. LÄS MER

  5. 4. A Novel Distributed Approach for Optimal Power Flow Problem in Smart Grids

    L3-uppsats, KTH/Reglerteknik

    Författare :Umberto Mosca; [2013]
    Nyckelord :;

    Sammanfattning : In this thesis we study a classical problem of the electrical field; the optimal power flow (OPF) in an electrical network. Given a power grid, the problem is to find the optimal production of generators respecting all the constraints imposed by physics, like Kirchhoff’ equations and power bounds on each part of network.
