This paper demonstrates a high performance brain-computer interface (BCI) that allows users to dial phone numbers. The system is based on Canonical Correlation Analysis (CCA) and Steady-State Visual Evoked Potential (SSVEP). Through six buttons (9Hz, 10Hz, 11Hz, 12Hz, 13 Hz, 14Hz) displayed on the screen, subjects can choose the number by gazing at the computer interface. This proposed EEG (Electroencephalography)...
While channel state information (CSI) at the transmitter is critical to the system capacity of multiple input multiple output (MIMO) broadcast channels, its acquisition is practically intricate. This paper exploits the benefit of receiver cooperation to render it unnecessary to acquire CSI at the transmitter. As a fundamental question, how many downlink transmission bits can one bit of receiver cooperation...
While channel state information (CSI) at the transmitter is critical to the system capacity of multiple input multiple output (MIMO) broadcast channels, its acquisition is practically intricate. This paper offers an alternative and investigates a special MIMO broadcast channel, which exploits the benefit of receiver cooperation and renders it unnecessary to acquire CSI at the transmitter. The cooperation...
Partial discharge (PD) measurement method defined in IEC60270 only captures the low frequency energy of measured signals, while more than 95% of the energy is distributed in the range of 30kHz∼30MHz. Thus a high frequency wide band measurement method becomes fashionable to cover the entire bandwidth. In such frequency range, the influence of stray inductance and capacitance become dominant, especially...
On-chip global interconnects are speed and power bottleneck in state-of-the-art chips. Pre-emphasis technique is an efficient way to improve the performance of the global communication. This paper first performs delay analysis of a global wire to work with a pre-emphasis circuit in time domain. Based on the analysis, a new pre-emphasis circuit design is proposed. Simulation results show that the pre-emphasis...
This paper studies the problem of non-cooperative joint channel and bandwidth allocations in multi-radio multichannel wireless networks. Existing works only studied non-cooperative multi-radio channel allocation and they did not consider two important issues, impact of traffic load to channel's transmission quality, and difference of bandwidth demands for different node pairs, which may have significant...
