Optimal estimation of ionosphere-induced group delays of global positioning satellite signals during launch, orbit and re-entry
… earth's surface. Among these is the ionospheric group delay. In the past, a single-state, dual-frequency filter has been used to estimate the ionospheric delay for authorized users. Although sufficient for terrestrial receivers for which the ionospheric delay changes very slowly, such a filter is …

Auditory-nerve fiber responses to amplitude modulated tones and multi-tonal stimuli
… theory provides a prediction between the SFOAE group delay and the group delays of tone responses on the basilar membrane within the cochlea. Using single and multiple-tone stimuli, we collected data from the firing patterns of single auditory-nerve-fibers (ANFs) from which basilar-membrane …

Low-frequency bias-tone effects on auditory-nerve responses to clicks and tones : investigating multiple outer-hair-cell actions on auditory-nerve firing
… Previous work found differences in AN-response group delays between CF and off-CF frequency regions that might arise from two different IHC-drive mechanisms, and the objective was to test this hypothesis. Our results showed similar bias-tone effects in both regions. Overall, the results …

Enhancing voice pitch perception in cochlear implants
Cochlear implants (CIs) are among the most successful sensory prostheses in the world, partially restoring hearing and, to many users, speech perception. However, they suffer in more complex tasks such as pitch perception. In particular, poor voice pitch perception affects CI users’ ability to …
