3. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. READ MORE

5. Reconfigurable Intelligent Surfaces : Optimal Positioning and Coverage Improvement
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Med framväxten av framtida mobilgenerationer bortom 5G, studeras nya teknologier för att tillgodose de förväntade kraven för framtida tjänster som Ultra-Reliable Low Latency Communications (URLLC) eller Virtual Reality. Bland dessa teknologier uppstår Reconfigurable Intelligent Surfaces (RIS) som en av de mest lovande på grund av deras förmåga att förbättra kanalen samtidigt som de bara ökar nätverkets energiförbrukning måttligt.
