1. 6. 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.

4. 8. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

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

   Author : Tomás Soares da Costa; [2019]
   Keywords : ;

   Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE

5. 9. Long Range Channel Predictions for Broadband Systems : Predictor antenna experiments and interpolation of Kalman predictions

   University essay from Uppsala universitet/Signaler och System

   Author : Joachim Björsell; [2016]
   Keywords : Channel prediction; Prediction interpolation; Predictor antenna; Predictor antenna measurements; Telecom; Telecommunication;

   Abstract : The field of wireless communication is under massive development and the demands on the cellular system, especially, are constantly increasing as the utilizing devices are increasing in number and diversity. A key component of wireless communication is the knowledge of the channel, i.e, how the signal is affected when sent over the wireless medium. READ MORE

6. 10. Ray-tracing based analysis of channel characteristics and capacity improvement capabilities of spatial multiplexing and beamforming at 15 and 28 GHz

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

   Keywords : 5G; 15 GHz; 28 GHz; beamforming; capacity; channel multiplexing richness; hybrid beamforming; MIMO; mm-Wave; ray-tracing; spatial multiplexing; Technology and Engineering;

   Abstract : In the previous decades, mm-Wave frequency bands have largely been ignored for cellular communication because of the high free space attenuation as well as the cost and complexity of mm-Wave RF circuits. However, with the improvement of RF and antenna technologies over the last decade, it has become feasible to con- sider mm-Wave bands for cellular communications. READ MORE
