Direct-sequence spread-spectrum acoustic communications with CRV Decomposition
(Monterey, California. Naval Postgraduate School, 2004-06)
Direct-Sequence Spread-Spectrum (DS-SS) is among the preferred modulation techniques for military applications. DS-SS offers three greatly desired characteristics. It allows for the development of Low Probability of Detection ...
Performance of acoustic spread-spectrum signaling in simulated ocean channels
(Monterey, California. Naval Postgraduate School, 2003-06)
Direct-Sequence Spread Spectrum (DSSS) modulation is being advanced as the physical-layer basis for Seaweb undersea acoustic networking. DSSS meets the need for channel tolerance, transmission security, and multi-user ...
Acoustic transient TDOA estimation and discrimination
(Monterey, California. Naval Postgraduate School, 2000-09)
This thesis examines acoustic transient discrimination and Time Difference Of Arrival (TDOA) estimation for the purposes of estimating the position of a submarine in a sonobuoy field. Transient discrimination, for this ...
