  1. 1. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

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

    Author : Hamid Yadegar Amin; [2020]
    Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

    Abstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

  2. 2. 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. 3. Intelligent Beam Weight Computation for Massive Beamforming

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling; Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Rohan Appilla Chakravarthula; Chaithanya Kumar Reddy Veluru; [2017]
    Keywords : ;

    Abstract : LTE (Long Term Evolution) is likely the most complex wireless system ever developed. It incorporates features that could not have been economically implemented as recently as a decade ago. Today, with large-scale ICs, LTE can be easily accommodated in base stations and battery-powered handsets alike. READ MORE

  4. 4. Channel Characteristics Variations from Switching Between Narrow Beams

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oscar Lundberg; [2017]
    Keywords : 5G; radio waves; telecommunication; antennas; beam forming;

    Abstract : The demand for higher throughput and lower latency in telecommunication systems is growing. Upcoming telecommunication systems will operate at higher frequencies (above 15 GHz) compared with previous systems (below 6 GHz). READ MORE

  5. 5. Maximizing LTE performance with MIMO Systems

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Vunnam Praveen; [2016]
    Keywords : ;

    Abstract : The project explains Long Term Evolution (LTE) systems when used with Multiple-Input, MultipleOutput (MIMO) fulfill the growing demands in throughput and system robustness for the user. This is investigated by understanding the throughput capacity of LTE down-links in both spatial multiplexing and transmission diversity mode. READ MORE
