1. 1. Hierarchical Clustering based Dynamic Subarrays for Hybrid Beamforming Massive MU-MIMO

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

   Author : Francisco Goncalves Contente; [2020]
   Keywords : ;

   Abstract : Hybrid Beamforming in multiple input multiple output systems has surged in the past few years as the prime precoding architecture for massive MIMO systems since it addresses the systems performance and complexity/power consumption tradeoff. Most of the literature addresses HBF MIMO with a fixed antenna subarray, however it is possible to further increase the spectral efficiency of the system by dynamically configuring the HBF MIMO subarray according the channel state information of the users.

3. 2. Design and optimization of Bandwidth Part selection for massive beamforming

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

   Author : Juan Guirado Lopez-Puigcerver; [2020]
   Keywords : Mobile communications; 5G; New Radio NR ; Bandwidth Part BWP ; Beamforming; MU-MIMO; Technology and Engineering;

   Abstract : In the last 30 years, a new mobile communications generation has been developed every 7 to 10 years. The last one that is currently under development is the Fifth Generation. This generation aims to fulfill a wide range of requirements for different use cases. To that end, a new radio access technology called New Radio (NR) has been developed. READ MORE

4. 3. Block Diagonalization Based Beamforming

   University essay from KTH/Teknisk informationsvetenskap

   Author : Darshan Patil; [2017]
   Keywords : ;

   Abstract : With increasing mobile penetration multi-user multi-antenna wireless communication systems are needed. This is to ensure higher per-user data rates along with higher system capacities by exploiting the excess degree of freedom due to additional antennas at the receiver with spatial multiplexing.

5. 4. A Scalable Architecture for Massive MIMO Base Stations Using Distributed Processing

   University essay from Linköpings universitet/Datorteknik

   Author : Erik Bertilsson; [2017]
   Keywords : Massiv MIMO; ASIC; Architecture;

   Abstract : Massive MIMO is an emerging technology for future wireless systems that has received much attention from both academia and industry recently. The most prominent feature of Massive MIMO is that the base station is equiped with a large number of antennas. READ MORE

6. 5. Pilot Contamination and Mitigation Techniques in Massive MIMO Systems

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

   Author : Vidit Saxena; [2014]
   Keywords : Multicell Systems; Massive MIMO; Pilot Contamination; LTE; Power Control; Resource Allocation; Channel Estimation; Precoding; Technology and Engineering;

   Abstract : A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. READ MORE
