Covert underwater acoustic communications
The Journal of the Acoustical Society of America, 2010 Low probability of detection (LPD) communications are conducted at a low received signal-to-noise ratio (SNR) to deter eavesdroppers to sense the presence of the transmitted signal. Successful detection at intended receiver heavily relies on the processing gain achieved by employing the direct-sequence spread-spectrum (DSSS) technique.

An overview of channel coding for underwater acoustic communications [PDF]
MILCOM 2012 - 2012 IEEE Military Communications Conference, 2012 The TRIDENT (TRansmission d'Images et de Donnees EN Temps reeel) project was launched a few years ago by GESMA (Groupe d'Etudes Sous Marine de l'Atlantique). The initial objectives were to develop a multiple-rate underwater acoustic link for images, text and data transmission. Later, the speech option was added, and more recently channel coding options

Nibble-CRC for Underwater Acoustic Communication [PDF]
, 2012 Underwater acoustic sensor networks (UWASNs) are complex in design due to the characteristics of underwater medium. The underwater communication environment and the medium vary on time, geographical location and depth. Sensor nodes are also born with some limitations such as fixed amount of energy, small size memory and node mobility.
