Transmitter Localization Without Clock Synchronization

Determining the location of a transmitting party in a communication network normally requires a number of identifying factors. The transmitting party can be located through triangulating their signal, using the signal’s arrival at several receivers to determine the transmission’s origin. One can also determine the location of a receiver by comparing the receipt of multiple transmitter signals; however, in both scenarios the transmitter and receiver must employ clock synchronization and signal time-of-travel information to accurately compute relative localization between the two.   The Global Positioning System is a well-known example of this process, leveraging known time (and synchronizing to that time) and position of each GPS satellite to deduce the location of a receiver.

High Electromechanical Coupling Disk Resonators

Capacitive-gap transduced micromechanical resonators routinely post Q several times higher than piezoelectric counterparts, making them the preferred platform for HF and low-VHF (e.g. 60-MHz) timing oscillators, as well as very narrowband (e.g. channel-select) low-loss filters. However, the small electromechanical coupling (as gauged by the resonator's motion-to-static capacitance ratio, Cx/Co) of these resonators at higher frequency prevents sub-mW GSM reference oscillators and complicates the realization of wider bandwidth filters. To address this situation, researchers at UC Berkeley developed a capacitive-gap transduced radial mode disk resonator with reduced mass and stiffness. This novel Berkeley disk resonator has a measured electromechanical coupling strength (Cx/Co) of 0.56% at 123 MHz without electrode-to-resonator gap scaling. This is an electromechanical coupling strength improvement of more than 5x compared with a conventional radial contour-mode disk at the same frequency. This increase should help improve the passbands of channel-select filters targeted for low power wireless transceivers and lower the power of MEMS-based oscillators.

The levels of long-term instabilities in bias and scale factor are key characteristics for the utilization of gyroscopes in many practical applications in navigation, positioning, and targeting systems. The inventors at UCI have developed two methods for gyroscope calibration: 1) Utilizing the mechanical quadrature error and 2) Utilizing the voltages of amplitude gain control (AGC) of the drive-mode. The new methods have been combined with feedback signals from a third technique, Side-Band Ratio (SBR) detection, to produce bias stability of 0.1 deg/hr after 300 seconds that is maintained for over 3 hours.

Secret Key Generation For Wireless Communication In Cyber-Physical Automotive Systems
