  2. 1. Detection for multiple input multiple output channels : analysis of sphere decoding and semidefinite relaxation

    Author : Joakim Jaldén; Björn Ottersten; Zhi-Quan Luo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunications; MIMO; Detection; Sphere Decoder; Semidefinite Relaxation; Telecommunication; Telekommunikation;

    Abstract : The problem of detecting a vector of symbols, drawn from a finite alphabet and transmitted over a multiple-input multiple-output (MIMO) channel with Gaussian noise, is of central importance in digital communications and is encountered in several different applications. Examples include, but are not limited to; detection of symbols spatially multiplexed over a multiple-antenna channel and the multiuser detection problem in a code division multiple access (CDMA) system.

  4. 2. Efficient MIMO Detection Methods

    Author : Mirsad Čirkić; Erik G. Larsson; John Thompson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For the past decades, the demand in transferring large amounts of data rapidly and reliably has been increasing drastically. One of the more promising techniques that can provide the desired performance is multiple-input multiple-output (MIMO) technology where multiple antennas are placed at both the transmitting and receiving side of the communication link.

  6. 4. Doctoral Thesis: Massive MIMO in Real Propagation Environments

    Author : Xiang Gao; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Massive MIMO; very-large MIMO; multi-user MIMO; channel measurements; channel modeling; 5G; sum-rate capacity; antenna selection; signal processing;

    Abstract : Mobile communications are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, sensors, connected vehicles and so on. Much higher data rates than in today's 4G systems are required. READ MORE
