  2. 11. Channel Prediction Based On Sinusoidal Modeling

    Author : Ming Chen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Long range channel prediction is considered as one of the most important enabling technologies to future wireless communication systems. The prediction of Rayleigh fading channels is studied in the frame of sinusoidal modeling in this thesis. A stochastic sinusoidal model to represent Rayleigh fading channel is proposed. READ MORE

  4. 12. Modeling of Multiple-Input Multiple-Output Radio Propagation Channels

    Author : Kai Yu; KTH; []
    Keywords : Antenna Array; Wireless Communications; MIMO Channel Model; MIMO Channel Measurements; MIMO Channel Capacity;

    Abstract : In recent years, multiple-input multiple-output (MIMO)systems appear to be very promising since they can provide highdata rates in environments with sucient scattering byexploiting the spatial domain. To design a real MIMO wirelesssystem and predict its performance under certain circumstances,it is necessary to have accurate MIMO wireless channel modelsfor dierent scenarios. READ MORE

  5. 13. Characterization of Single- and Multi-antenna Wireless Channels

    Author : Shurjeel Wyne; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; channel measurements; channel modeling; Wireless propagation; sensor networks;

    Abstract : The wireless propagation channel significantly influences the received signal, so that it needs to be modeled effectively. Extensive measurements and analysis are required for investigating the validity of theoretical models and postulating new models based on measurements. Such measurements, analysis, and modeling are the topic of this thesis. READ MORE

  6. 14. 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

  7. 15. Vehicular Communication in Obstructed and Non Line-of-Sight Scenarios

    Author : Dimitrios Vlastaras; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-to-Vehicle Communications; Channel Modeling; Vehicular Communication; Truck Obstruction; Channel Emulation; Radar; 802.11p; Car; Truck; Accident Avoidance; V2V; V2I; C2C; V2X;

    Abstract : Since the invention of the first car available to masses, the 1908 Ford Model T, technology has advanced towards making car travel safer for occupants and bystanders. In recent years, wireless communication has been introduced in the vehicular industry as a means to avoid accidents and save lives. READ MORE
