Phase-shift keying of EEG signals: Application to detect attention in multitalker scenarios
We propose an M-PSK model for the detection of auditory attention in a multitalker scenario. We generate an M-PSK constellation from EEG signals. For a robust detection, we embed attention in M-PSK symbols. Our approach extends dichotic listening task to 4 and 6 talkers. Methodology could be applied in neuromarketing, attention assessment and for BCIs.
