The cost of space independence in P300-BCI spellers. [PDF]
, 2010 Background: Though non-invasive EEG-based Brain Computer Interfaces (BCI) have been researched extensively over the last two decades, most designs require control of spatial attention and/or gaze on the part of the user. Methods: In healthy adults, we

Covert Rate Study for Full-Duplex D2D Communications Underlaid Cellular Networks
IEEE Internet of Things Journal, 2023 Abstract Device-to-device (D2D) communications underlaid cellular networks have emerged as a promising network architecture to provide extended coverage and high data rate for various Internet of Things (IoT) applications. However, because of the inherent openness and broadcasting nature of wireless communications, such networks face severe risks of ...
