This project seeks to increase the power delivered to passive backscatter RF tags using transmit diversity – a method that uses multiple antennas and channel knowledge to deliver power to the tag.
We have demonstrated an increase in the power incident on the RF tag using transmit diversity in a monostatic backscatter channel.
For passive backscatter radio frequency identification (RFID) systems, the power incident on the radio frequency (RF) tag can be improved by applying transmit diversity.
In this paper, we study the mobility of visitors based on GPS traces collected in two entertainment parks.
In this paper, we study the mobility of visitors based on GPS traces collected in an entertainment theme park.
The acoustic capabilities (i.e. microphone) and the fast processors of modern smartphones allow for the transmission of data to groups of such devices through the audio channel. We discuss an acoustic data transmission system for broadcast communication to a multitude of smartphones without the need of a radio access point.
This paper designs a quality-aware coding and relaying algorithm for maximization of the overall video quality.
