Full-Duplex Underwater Networking Using CDMA

This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A451224. The abstract provided by the Pentagon follows: Establishing a full-duplex underwater network, researching and applying a CDMA protocol to the network, providing a recommendation for a full- duplex underwater network and providing recommendations for using CDMA to increase the efficiency of this network are the general scope of this thesis.. A connection that allows traffic in both directions simultaneously underwater is the example of full-duplex communication. Compared to a half duplex configuration, the full duplex network underwater may provide a better networking environment. Currently, most Underwater Acoustic Networks (L)ANs) still utilize half duplex network communication. CDMA is the third kind of channel partitioning protocol. Most of the wireless communication devices utilize different kinds of CDMA protocol as a reliable and faster communication. The research conduct in establishing a full-duplex LAN using CDMA may provide reliable and faster communication compared to half duplex.
