RADE for Land Mobile Radio: A Neural Codec for Transmission of Speech over Baseband FM Radio Channels
David Rowe, Tibor Bece
In the 1990s Land Mobile Radio (LMR) systems evolved from analog frequency modulation (FM) to standardised digital systems. Both digital and analog FM systems now co-exist in vario…
Speckle Interferometry of 25 Gaia Two-Parameter Potential Binaries
Paul McCudden, Russell Genet, John Major +20
Gaia two-parameter (G2P) stars have cumulative errors in parallax and proper motion so great that only their mean positions were reported in DR3. One potential cause of these high…
Evidence Estimation in Gaussian Graphical Models Using a Telescoping Block Decomposition of the Precision Matrix
Anindya Bhadra, Ksheera Sagar, David Rowe +2
Marginal likelihood, also known as model evidence, is a fundamental quantity in Bayesian statistics. It is used for model selection using Bayes factors or for empirical Bayes tunin…
RADE: A Neural Codec for Transmitting Speech over HF Radio Channels
David Rowe, Jean-Marc Valin
Speech compression is commonly used to send voice over radio channels in applications such as mobile telephony and two-way push-to-talk (PTT) radio. In classical systems, the speec…
Automated Speckle Interferometry of Known Binaries
Nick Hardy, Leon Bewersdorff, David Rowe +21
Astronomers have been measuring the separations and position angles between the two components of binary stars since William Herschel began his observations in 1781. In 1970, Anton…
The Renovated Thacher Observatory and First Science Results
Jonathan J. Swift, Karina Andersen, Toby Arculli +38
Located on the campus of the Thacher School in Southern California, the Thacher Observatory has a legacy of astronomy research and education that dates back to the late 1950's. In…
