1. 6. Efficient High-level Synthesis Implementation of massive MIMO Processing on RFSoC

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

   Author : Sijia Cheng; [2022]
   Keywords : Technology and Engineering;

   Abstract : Massive multiple-input multiple-output (MIMO) refers to a wireless access technology that equips base station (BS) with hundreds to thousands of antennas to serve tens of user equipment (UE) in the same time-frequency resource. These extensive antennas improve spectral and energy efficiency, but the detection algorithms tend to be more complex with operations, multiplications, and inversions on larger size matrix.

3. 7. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Johan Kövamees; [2020]
   Keywords : Electrically Steerable Phased-Arrays for 5G Sub-6 GHz Massive MIMO Active Antenna Units;

   Abstract : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. READ MORE

4. 8. PLL for 5G mmWave

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

   Author : Daniel Bakic; Jinzhuo Wu; [2020]
   Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

   Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE
