Most of the existed methods for steady-state visual evoked potential (SSVEP) recognition require a specified time window length (TWL) to estimate the dominant frequency components in EEG signals. Typically, the TWL is manually predetermined and then fixed during running of the SSVEP-based brain-computer interface (BCI), which may not give the optimal information transfer rate (ITR). This study proposes...
This paper proposes a coarse time synchronization method which reduces the influence of the inter symbol interference(ISI) for MIMO-OFDM systems. The proposed method extracts the timing which is not disturbed by delay spread within the guard interval (GI) by utilizing the cyclic prefix (CP). Thus, the proposed method is effective in reducing the influence of the ISI. Simulation results demonstrate...
