Line-of-Sight Obstruction Analysis for Vehicle-to-Vehicle Network Simulations in a Two-Lane Highway Scenario
Taimoor Abbas, Fredrik Tufvesson
In vehicular ad-hoc networks (VANETs) the impact of vehicles as obstacles has largely been neglected in the past. Recent studies have reported that the vehicles that obstruct the l…
Time- and Frequency-Varying -Factor of Non-Stationary Vehicular Channels for Safety Relevant Scenarios
Laura Bernadó, Thomas Zemen, Fredrik Tufvesson +2
Vehicular communication channels are characterized by a non-stationary time- and frequency-selective fading process due to fast changes in the environment. We characterize the dist…
Delay and Doppler Spreads of Non-Stationary Vehicular Channels for Safety Relevant Scenarios
Laura Bernadó, Thomas Zemen, Fredrik Tufvesson +2
Vehicular communication channels are characterized by a non-stationary time- and frequency-selective fading process due to rapid changes in the environment. The non-stationary fadi…
Massive MIMO for Next Generation Wireless Systems
Erik G. Larsson, Ove Edfors, Fredrik Tufvesson +1
Multi-user Multiple-Input Multiple-Output (MIMO) offers big advantages over conventional point-to-point MIMO: it works with cheap single-antenna terminals, a rich scattering enviro…
