1. 6. Acceleration of Massive MIMO algorithms for Beyond 5G Baseband processing

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Ellen Nihl; Eek de Bruijckere; [2023]
   Keywords : embedded systems; massive MIMO; GPU; massive MIMO detection; Zero-Forcing algorithm; Cholesky decomposition; CUDA; 5G and Beyond;

   Abstract : As the world becomes more globalised, user equipment such as smartphones and Internet of Things devices require increasingly more data, which increases the demand for wireless data traffic. Hence, the acceleration of next-generational networks (5G and beyond) focuses mainly on increasing the bitrate and decreasing the latency. READ MORE

3. 7. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

   University essay from Umeå universitet/Institutionen för fysik

   Author : Ossian Kynman; [2023]
   Keywords : MIMO; Diversity Gain; Capacity; Correlation; Fading;

   Abstract : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. READ MORE

4. 8. Beam-steered Modulation in Advanced Antenna System

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