1. 6. Beamforming Solutions for Efficient Link Setup and Link Maintenance in mmWave Communication Systems

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

   Author : Hesham Sharkas; Haruhi Echigo; [2019]
   Keywords : 5G; Beamforming; Beam-forming; Beam Management; Beam Searching; Beam Sweeping; Codebook; code-book; Initial Access; MIMO; MillimeterWave; millimeter wave; mmWave; mm-Wave; mm Wave; Precoding; Slepian Beam; Synthesizer; Beam Synthesizer; Technology and Engineering;

   Abstract : Millimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. READ MORE

3. 7. Scheduler Algorithms for MU-MIMO

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

   Author : Wissam Moustafa; Richard Mugisha; [2017]
   Keywords : Scheduling; Beamforming; TDD; TM-8; SRS; Downlink; Round Robin; SU-MIMO; MU-MIMO.; Technology and Engineering;

   Abstract : In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. READ MORE

4. 8. 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. 9. Robust MIMO Precoding on Real-World Measured Channels

   University essay from KTH/Signalbehandling

   Author : Filip Hedenskog; [2015]
   Keywords : MIMO; maximin; imperfect CSIT; real-world measured channels; uncertainty set; worst-case robustness;

   Abstract : It is well known that multi-input multi-output (MIMO) wireless communication systemsthat employ precoding techniques are capable of meeting the high expectations of modernand future wireless communication standards. In order to fully utilize these techniques, thecommunication system typically requires information of the channel, commonly referred toas channel state information (CSI). READ MORE

6. 10. 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
