  1. 6. 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.

  3. 7. Black-Box Modeling and Attitude Control of a Quadcopter

    University essay from Linköpings universitet/Reglerteknik

    Author : Ingrid Kugelberg; [2016]
    Keywords : Attitude Control; Black-Box Modeling; Closed-Loop Identification; Multicopter; PID; Quadcopter; System Identification; UAV;

    Abstract : In this thesis, black-box models describing the quadcopter system dynamics for attitude control have been estimated using closed-loop data. A quadcopter is a naturally unstable multiple input multiple output (MIMO) system and is therefore an interesting platform to test and evaluate ideas in system identification and control theory on.

  4. 8. A Study of Lattice Reduction Detection Techniques for LTE Systems

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

    Author : Liping Wang; [2016]
    Keywords : LTE; MIMO; Lattice Reduction; MMSE; ZF; ML; Kronecker Model; Rayleigh Fading Channel; Technology and Engineering;

    Abstract : MIMO (Multiple Transmit and Multiple Receive) antenna techniques are widely used in the most recent wireless communication standards. For example, LTE (Long-Term Evolution), WiMAX (Worldwide Interoperability for Microwave Ac- cess) and IEEE 802.11n have recently been rolled out across the world. READ MORE

  5. 9. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

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

    Author : Rui Ma; Ioannis Chountalas; [2015]
    Keywords : Technology and Engineering;

    Abstract : Nowadays, multiple antennas are becoming widely used in small mobile terminals as they can significantly improve wireless communication performance in terms of link reliability and spectral efficiency. Also, pattern reconfiguration is another new trend for antenna design as it enables the antennas to adapt to different propagation and user scenarios. READ MORE

  6. 10. Massive MIMO Channel Modeling

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

    Author : Yongchun Wang; Xin You; [2015]
    Keywords : massive MIMO; 5G; channel modeling; the Kronecker model; the Weichselberger model; capacity; sum-rate; singular value spread; the Random Cluster Model; cluster; spatial correlation; large-scale fading; Technology and Engineering;

    Abstract : Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e. READ MORE
