  5. 4. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ossian Kynman; [2023]
    Keywords : MIMO; Diversity Gain; Capacity; Correlation; Fading;

    Abstract : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. READ MORE

  6. 5. Improving the Robustness of Over-the-Air Synchronization for 5G Networks in a Multipath Environment

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