1. 11. Beamforming in 5G mm-wave radionetworks : Importance of frequency multiplexing for users in urban macro environments

   University essay from Uppsala universitet/Signaler och system

   Author : Carl Lutnaes; [2020]
   Keywords : ;

   Abstract : 5G brings a few key technological improvements compared to previous generations in telecommunications. These include, but are not limited to, greater speeds, increased capacity and lower latency. These improvements are in part due to using high band frequencies, where increased capacity is found.

III-V nanowire MOSFETs are a promising device technology well suited for implementation of switches. READ MORE

5. 14. Near-Field Measurement System for 5G Advanced Antenna System at mm-Wavelength

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Bofei Wang; [2020]
   Keywords : Near-field; Measurement system; 5G; mm-wave length; antenna; Technology and Engineering;

   Abstract : An antenna is one of the most fundamental elements of wireless communication systems. The radiation behavior of antennas is characterized with the aid of the farfield radiation pattern. In this thesis, a near-field antenna measurement system is designed to predict the far-field pattern of antenna operational frequency 28 GHz and 39 GHz. READ MORE

6. 15. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Hamid Yadegar Amin; [2020]
   Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

   Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios. READ MORE
