Abstract: Methods, systems, and devices for wireless communication are described to support reducing a time domain selectivity of a downlink channel with multiple signal paths. A base station may spatially precode multiple channel state information reference signals (CSI-RSs) and transmit the spatially precoded CSI-RSs to a user equipment (UE), where at least one spatially precoded CSI-RS may correspond to each signal path. Based on the spatially precoded CSI-RSs, the UE may determine a mean or average Doppler shift for each signal path. The UE may transmit, to the base station, signaling indicative of the respective average Doppler shifts for each signal path. Based on the indication of the Doppler shifts, the base station may spatially and temporally precode one or more downlink transmissions to the UE, which may reduce the time domain selectivity of the downlink channel.

Abstract: A multi-source domain adaptive electroencephalogram (EEG) emotional state classification method based on knowledge distillation are provided. First, data is obtained for band-pass filtering, and artifacts are removed by an independent component analysis technology. Second, EEG features are extracted by using a differential entropy method, and a three-dimensional EEG time series is converted into a two-dimensional sample matrix. Then, a training set and a test set are defined in two task scenarios, respectively. A pseudo-label triple loss based on marginal sampling is combined with a maximum mean discrepancy. Knowledge is learned from different source domains, so that a plurality of single-source models are utilized to the greatest extent, and a more powerful model is implemented with less time consumption. Finally, the classification accuracy is used to evaluate the performance of the model in the two task scenarios.
