The variety in wireless technology and mobile computing devices has caused a growing application of location-sensing systems and correspondence services. The indoor location sensing system which applies radio frequency identification technology (RFID) is the most popular research topic in the area of location-sensing systems, and LANDMARC is the most representative one. However, LANDMARC suffer...

Traditional local active noise control systems minimise the measured acoustic pressure to generate a zone of quiet at the physical error sensor location. The resulting zone of quiet is generally limited in size and this requires the physical error sensor be placed at the desired location of attenuation, which is often inconvenient. To overcome this, a number of virtual sensing algorithms have b...

In this paper, a synchronization signal appropriate for small cell networks (SCNs), generated by a base station with 3D beamforming, is proposed for efficient handover in SCN. The synchronization signal carries a macro-cell ID (MCID) and virtual-cell ID (VCID) in a hierarchical manner, allowing us to distinguish between an intra-cell handover (virtual cell handover within a cell without changin...

We image a rat cerebral cortex in situ by using a ring-based ultrasonic virtual point detector developed previously. Compared to the image generated by a finite-aperture detector, the image generated by the virtual point detector has a uniformly distributed resolution throughout the imaged area, owing to the lack of aperture effect of the ultrasonic detector. At the periphery of the image, the ...
