Abstract

Abstract:

Joint design of the carrier frequency offset (CFO) estimator and adaptive training sequence for multiinput multioutput orthogonal frequency division multiplexing (MIMO-OFDM) system is investigated. With adaptive training sequence, which is optimized according to channel state information (CSI) available at the transmitter, proposed CFO estimator can update Schenks estimator and then reduce the effect of channel noise and further increase the accuracy of CFO estimation in fading channels.

Key words: multi-input multi-output orthogonal frequency division multiplexing, frequency synchronization, carrier frequency offset, training sequence
