In this deliverable, smart antenna based interference mitigation methods for WINNER are presented. These methods include beamforming techniques, transmit diversity techniques, and receive diversity and spatial interference suppression techniques. The methods are investigated in terms of what requirements they put on the system, and the performance they can achieve are assessed by means of compu...
Attentional interference by threat is associated with PTSD, but the mechanisms of this relationship remain unclear. Attentional interference might be related to increased use of maladaptive thought control strategies, such as suppressing unwanted thoughts (thought suppression) or replacing threatening thoughts with everyday concerns (worry), which increase PTSD risk. Conversely, attentional int...
Orthogonal frequency division multiplexing (OFDM) is a promising technique for high-data-rate wireless communications because it can combat inter-symbol interference (ISI) caused by the dispersive fading of wireless channels. The proposed research focuses on techniques that improve the performance of OFDM based wireless communications and its commercial and military applications. In particular,...
Inhibitory control is a core function that allows us to resist interference from our surroundings and to stop an ongoing action. To date, it is not clear whether inhibitory control is a single process or whether it is composed of different processes. Further, whether these processes are separate or clustered in childhood is under debate. In this study, we investigated the existence and developm...
Radio frequency interference (RFI) is greatly harmful to Global Navigation Satellite System (GNSS) receivers. Sweep one of the RFI for GNSS receivers, which can degrade performance receivers seriously. In this paper, Fractional Fourier Transform (FrFT) time-frequency analysis proposed in detection and suppression. The FrFT method tested detecting suppressing sweep interference, generated by a j...
