Kurzfassung:

In transmission scenarios where the transmitter and/or receiver move at very high velocities, the performance of an OFDM-based transmission system can severely suffer from the effects of Doppler. In the presented paper, we therefore propose the application of a low-complexity sorted QR decomposition of the channel interference matrix in order to suppress the intercarrier interference resulting from high Doppler spreads. The hereby achievable system performance improvements compared to existing MMSE and MMSE-DFE approaches are shown in our simulation results.
