This paper presents a novel double-differentially coded spread-spectrum (DD-SS) system design for long-range acoustic communications (LRAC) between a moving source and a towed horizontal line array (HLA). The proposed design relies on two techniques

An asynchronous multiuser system is proposed to support multiple-access underwater communications without the use of code-division multiple-access or a feedback channel. The rich multipath channels experienced by spatially separated users will be suf

In this letter, an adaptive time-reversal multichannel combiner is embedded within an iterative successive interference cancellation receiver. With the addition of matching pursuit, a sparse channel estimation technique, the combined receiver is show

In this paper, we introduce the addition of an iterative, successive interference cancellation (SIC) process to improve on a multiuser, single-input-multiple-output (SIMO) communications receiver using passive time reversal as a space-time preprocess

A multiuser receiver is developed that is capable of separating receptions from independent, mobile users whose transmissions overlap in both time and frequency. With respect to any one user's Doppler corrected signal, the other communication signals

In September 2010 a long-range acoustic communication (LRAC10) experiment was carried out in deep water off the Southern California Coast. The experiment involved two mobile components: (1) a source towed slowly at a speed of 2–3 knots at ∼75-m d

In this paper, we propose a communications receiver architecture composed of a time-reversal approach to simplify the shallow underwater acoustic channel and to suppress multiuser interference followed by an iterative, successive interference cancell
