Bran-machine interface (BMI) can be used for controlling of external devices such as the exoskeleton, robot arm, etc. For efficient communication between a user and machine, fast and accurate detection of user intention is important elements in the BMI application. For this reason, readiness potential (RP) is a useful feature that is possible to detect movement intention before the movement onset...
Recently, there has been an increased demand for Brain-Machine Interface (BMI) toolboxes for neuroscientifc research. In many BMI applications, speller systems can provide an efficient communication channel for users with disabilities. Here, we introduce an open-source BMI toolbox termed ‘OpenBMI’, which supports the various signal processing chains for common BMI paradigms, such as event-related...
In this paper, a novel probe-exciting feed structure was proposed for improving the bandwidth of a waveguide broad wall slot array antenna. Both a conventional inclined slot feed and the proposed one are applied to the design of the broad wall slot arrays with the same specification, respectively, and then, their results are compared by using the full-wave EM simulation. As expected, the bandwidth...
This paper presents a balanced K-band (18 to 27 GHz) Self-Oscillating Mixer (SOM) with 0.18 ??m CMOS technology. The proposed SOM employs a push-push configuration for the oscillating function which is designed to operate at K-band. Using the push-push configuration, a K-band frequency of 22.57 GHz is achieved. The proposed SOM uses an RF frequency of 23 GHz, and generates a self-oscillation frequency...
The characteristics of ultra-wideband (UWB) channels in vehicular environments are explored. A set of propagation measurements were conducted on roadways and in underground parking garages and the resulting propagation data consists of approximately 1,200 multipath profiles. The channel impulse responses are estimated from the measured data using generalized maximum likelihood. The statistics of channel...
