Multicarrier Transmission for Scenarios with High Doppler Influence

Autoren:

Kurzfassung:

OFDM is an efcient transmission technique for frequency selective channels, but can severely suffer from the effects of Doppler, if the transmitter and/or receiver move with high velocities. In this paper, we present a multicarrier system with soft impulse shaping and tailbiting Max-Log-MAP equalization in order to suppress the intercarrier interference caused by Doppler. With simulation results we demonstrate the achievable performance improvements compared to a conventional OFDM system.
