Ranging Performance for Spoofer Localization using Receiver Clock Offset

Network Time Synchronization Using Clock Offset Optimization

Using Programmable Logic for Receiver Offset and Yield Enhancement

As the chip manufacturing process scales down to smaller nodes, random offsets due to the statistical variations of fabrication are undermining performance, especially for analog/mixed signal circuitry. This paper presents a methodology for offset cancellation for the receive path of a programmable logic device (PLD) integrated wide-range transceiver. The transceiver was designed and fabricated...

GNSS Receiver Identification Using Clock-Derived Metrics †

Falsifying Global Navigation Satellite System (GNSS) data with a simulator or with a fake receiver can have a significant economic or safety impact in many transportation applications where Position, Velocity and Time (PVT) are used to enforce a regulation. In this context, the authentication of the source of the PVT data (i.e., the GNSS receiver) is a requirement since data faking can become a...

Effect of clock offset on an impulse radio ultra wideband ranging system with comparators

Impulse radio ultra wideband (IR-UWB) can achieve high resolution in ranging because it uses a very short pulse with a duration of less than 1 ns. In order to reduce cost and power consumption, a ranging system with high-speed comparators has been proposed. In this system, it is necessary to reduce noise power through averaging the comparator outputs. The authors evaluate the effect of clock of...

Effects of Transmitter Symbol Clock Jitter Upon Ground Receiver Performance

In this article we characterize the effect of transmitter clock jitter upon receiver symbol synchronization performance. Using a sinusoidal model for the timing jitter, we evaluate the bit error rate (BER) degradation and cycle slip probabilities of receivers via analysis as well as simulation for uncoded offset quadrature-phase-shift-keying (OQPSK). We evaluate performance for two different sy...
