    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Farnaz Gharari; [2015]
    Keywords : Cooperative communications; Relay Networks; Rayleigh channels; Radio communication Protocols; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : The rapid changes and developments in cellular and wireless networks aim to provide more reliable communications with high data rate transmission. So far, one solution which is being considered for improving the reliability and eciency of mobile communications is cooperative communications. READ MORE

  3. 17. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance

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

    Author : Xi Chen; [2015]
    Keywords : V2V; wireless; channel model; multilink; relaying; sum of sinusoids; correlated Gaussian; maximum likelihood estimation; Technology and Engineering;

    Abstract : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). READ MORE

  4. 18. 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

  5. 19. Filter Bank Multi-Carrier Modulation

    University essay from KTH/Kommunikationsteori

    Author : Frédéric De Poret; [2015]
    Keywords : ;

    Abstract : During the last years, multi-carrier modulations have raised a particular interest due to their high spectral efficiency and the possible assumption of flat frequency fading. The most broadly used multi-carrier modulation is the CP-OFDM. READ MORE

  6. 20. Robust MIMO Precoding on Real-World Measured Channels

    University essay from KTH/Signalbehandling

    Author : Filip Hedenskog; [2015]
    Keywords : MIMO; maximin; imperfect CSIT; real-world measured channels; uncertainty set; worst-case robustness;

    Abstract : It is well known that multi-input multi-output (MIMO) wireless communication systemsthat employ precoding techniques are capable of meeting the high expectations of modernand future wireless communication standards. In order to fully utilize these techniques, thecommunication system typically requires information of the channel, commonly referred toas channel state information (CSI). READ MORE
