Abstract: A system and method for implementing a distributed source coding quantization scheme is provided. In one example, two independent but statistically correlated data sources can be asymmetrically compressed so that one source is compressed at a higher ratio than the other. The resulting signals are transmitted and decoded by a receiver. The highly compressed source can utilize the non-highly compressed source as side information so as to minimize the compression loss associated with the higher compression ratio. A conditional codebook can be created that not only depends on the highly compressed quantizer, but also depends on the quantized symbol received from the non-highly compressed data source.

Abstract: Systems and methods for classifying a modulation scheme of a wireless signal are described. In some embodiments, a system receives a wireless signal modulated based on a modulation scheme having a constant modulus. The system can generate a resampled signal from the wireless signal based on features extracted from the wireless signal and perform blind equalization on the resampled signal based on a constant modulus criterion to generate an equalized signal. Then, the system can cause a modulation classifier to classify the received wireless signal to a modulation scheme from a plurality of predetermined modulation schemes based on the equalized signal. By preconditioning the wireless signal to reduce feature variability imparted by a propagation channel onto the wireless signal, the system can increase the classification accuracy of the modulation classifier.

Abstract: Provided herein are systems and methods for synchronizing clocks and determining a range distance between two clocks using one or more timing signals that are communicated between the clocks. The determination can be made to also account for movement between the clocks such as if the clocks are converging (i.e., the distance between them is decreasing over time) or diverging (i., the distance between the clocks is increasing over time.) The systems and methods can utilize timing signals transmitted between two clocks that are synchronizing with another using the precision time protocol. In order to account for the increasing or decreasing distance between the clocks, the systems and methods can utilize Doppler shift data taken between the clocks to apply a correction factor to the timing signals. The timing signals and correction factor can be utilized to also determine a range distance between the clocks.
