Antenna Arrays for 5G Radio Access Networks
Predavanje je otvoreno za sve zainteresirane, a posebno pozivamo studente.
5G New Radio (NR) provides wireless connectivity for a wide range of new applications having vastly different requirements, such as massive system capacity, low latency and low jitter, high data rates, and low energy consumption. The 5G NR meets these requirements by employing higher frequency bands, massive MIMO transmission, beamforming, and ultra-lean design. Here, we consider beamforming. It utilizes a massive MIMO antenna array to increase the capacity and effectiveness of radio transmissions. The array emits radio signals using highly focused, steerable beams which deliver a stronger radio signal to a greater distance and with less energy. In this lecture, common and advanced array design techniques are presented. Concepts of analog and digital beamforming and beam steering are described. In early development phases, digital parts of radio base systems are designed as RF SoCs and integrated into all-programmable system-on-chip devices. Here, an example of the radio transceiver implementing RF SoC and employing an array having several hundred antennas is given.
Marko Matijascic received the Master degree in Electrical engineering and information technology from the University of Zagreb Faculty of Electrical Engineering and Computing, Zagreb, Croatia, in 2018. After the Master study, he has been employed in the Research and Development Centre of Ericsson Nikola Tesla d.d. in Zagreb, where he works as Software/Hardware Developer in the Radio Development Unit. In the unit, he is also a member of the Scientific Radio group, where he participates in various research activities. His research interests are in the field of analog and digital beamforming as well as antenna array design for massive MIMO applications. He is a member of IEEE societies on Signal Processing, Antennas and Propagation, and Circuits and Systems.
