  1. 1. Spectrum Sensing Algorithms Based on Second-Order Statistics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Erik Axell; Erik G. Larsson; Jan-Åke Larsson; Danyo Danev; Visa Koivunen; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cognitive radio is a new concept of reusing spectrum in an opportunistic manner. Cognitive radio is motivated by recent measurements of spectrum utilization, showing unused resources in frequency, time and space. Introducing cognitive radios in a primary network inevitably creates increased interference to the primary users. LÄS MER

    Sammanfattning : The last ten years have seen significant advances of multiuser MIMO (MU-MIMO) in wireless communication. MU-MIMO is now being introduced in several new generation wireless standards (e.g.,LTE-Advanced, 802. LÄS MER

  4. 4. Resource Allocation on the MISO Interference Channel

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Johannes Lindblom; Erik G. Larsson; Mats Bengtsson; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The need for wireless communications has increased during the last decades. To increase the data rates of the communication links there is a need of allocating larger frequency bands. These bands are strictly regulated and the majority of the frequencies are allocated to licensed systems. LÄS MER

  5. 5. Analysis of Cellular and Cell-Free Massive MIMO with Rician Fading

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Özgecan Özdogan; Emil Björnson; Erik G. Larsson; Sofie Pollin; [2020]
