Seismic oceanography of internal solitary waves offshore the South Island, New Zealand

Frontiers in Marine Science
Seismic oceanography has been widely used in the study of internal solitary waves (ISWs) in recent years, and has achieved remarkable results. In this paper, we analyzed the multi-channel seismic reflection data in the Canterbury Basin offshore New ...

A Multiband Excited Waveform-Interpolated 2.35-kbps Speech Codec for Bandlimited Channels

, 2000
Following a brief portrayal of the activities in 2.4-kbps speech coding, a wavelet-based pitch detector is invoked, which reduces the complexity of conventional autocorrelation-based pitch detectors, while ensuring smooth pitch trajectory evolution. This

Novel Use of Intracranial Arterial Pressure Waveforms to Detect Occlusive Events During Neuroendovascular Treatment

Stroke: Vascular and Interventional Neurology
BACKGROUND Unexpected occlusive events, such as thrombosis, can cause serious complications during neuroendovascular treatment. Angiography provides only intermittent assessments, potentially missing rapidly developing occlusions, highlighting the need ...

Multiple sets of solutions for harmonic elimination PWM bipolar waveforms: Analysis and experimental verification

, 2006
Multiple sets of solutions for the selective harmonic elimination pulse-width modulation method for inverter control exist. These sets present an independent solution to the same problem but further investigation reveals that certain sets may offer an ...

Evaluation of Waveform Candidates for 5G Wireless Communications [PDF]

, 2019
In this paper, we evaluate the waveform candidates for 5G wireless communications such as FBMC and UFMC and 4G’s cyclic prefix CP-OFDM. Measured results for 1.4 MHz and 3 MHz waveforms show a 5 dB reduction in ACPR between FBMC and UFMC.
