Impact of sea waves on performance of shallow water acoustic communications

2016 IEEE/OES China Ocean Acoustics (COA), 2016

Shallow water acoustic channels have fast time-variance, long-time multipath spread and large Doppler shift. Their transfer characteristics are influenced by many factors, such as: the operating frequency; the acoustic characteristics of sea surface and bottom; the ocean sound speed profile; the water depth; the depth and distance between the transmitters and the receivers; the variations of channel boundary; and, subsea ...

Preamble Design with HFMs for Underwater Acoustic Communications

2018 OCEANS - MTS/IEEE Kobe Techno-Oceans (OTO), 2018

Hyperbolic frequency modulation (HFM) is Doppler insensitive. Therefore, HFM has been widely used in underwater acoustic communications as a preamble where wideband Doppler insensitivity is highly required. Based on this, we propose a new waveform named up-down-sweeping HFM (UMD-HFM). It combines an up-sweeping HFM and a down-sweeping HFM and leaves a span which is a little longer than delay spread ...

  • Impact of sea waves on performance of shallow water acoustic communications

    Shallow water acoustic channels have fast time-variance, long-time multipath spread and large Doppler shift. Their transfer characteristics are influenced by many factors, such as: the operating frequency; the acoustic characteristics of sea surface and bottom; the ocean sound speed profile; the water depth; the depth and distance between the transmitters and the receivers; the variations of channel boundary; and, subsea objects. A time- varying channel impulse response has both deterministic and stochastic characteristics in a shallow water environment. Given the ocean environmental parameters, the deterministic impulse response can be calculated exactly by using underwater sound propagation models. However, it is extremely difficult to predict the stochastic impulse response due to its complexity. The method of ray tracing is quicker and more efficient than other methods such as with normal modes, parabolic equation and wave number integration in order to predict underwater water acoustic channels. At high frequencies, the ray tracing method is as accurate as others. Therefore, the ray tracing method has been widely used to simulate the channel impulse response in underwater acoustic communications. Here we focus on the impact of sea waves on the performance of single-carrier coherent underwater acoustic communications. Assuming that the sea wave is a single sinusoidal wave, we modify the BELLHOP ray module included in the Acoustic Toolbox in order to calculate the time- varying channel impulse response in a shallow water environment. Four time- varying channel impulse responses are presented for sea waves with a wave length of 50.0 m, and wave heights of 0.0, 0.5, 1.0 and 2.0 m. Furthermore, we investigate the impact of the wave height on the performance of the single- carrier coherent underwater acoustic communication system. Simulations demonstrate that bit error rates (BERs) of the system remain unchanged with time when the wave height equals 0.0 m. However, BERs change rapidly with time when the wave height is greater than 0.0 m. The higher the wave height, the faster the channel impulse response changes with time, and as a result, the higher the mean BER.

  • Undersea remote sensing with acoustic communications waveforms

    Coherence under varied circumstances is compared for two classes of waveform: linear FM chirps (a conventional sonar waveform) and binary phase shift keyed messages (a conventional acoustic communications waveform). All but the waveforms' time domain structure is kept constant during the comparison. Both modeled results as well as data from a large undersea array of hydrophones are presented. Parameters considered include bandwidth, pulse length, range from transmitter, and ray path. We find that if the ray interacts with the ocean surface, the resulting Doppler shift quickly destroys coherence for the BPSK waveform, which is highly Doppler intolerant. However, additional processing can mitigate this issue, and remote sensing with acoustic communications networks is a topic of interest.

  • Chaotic modulation detection for underwater acoustic communications via instantaneous features

    Modulation detection is important for underwater military communications and warfare applications. Chaotic modulations based on chaotic sequences are proposed to protect confidential underwater communications. In this paper, we develop a detection algorithm employing instantaneous phase and frequency for underwater acoustic communications. The key features derived from instantaneous phase and frequency are used to detect two chaotic modulations. They are chaotic M-ary phase shift keying (CMPSK) and chaotic M-ary frequency shift keying (CMFSK), which are designed to provide confidential underwater communications. Simulation and experimental results confirm the effectiveness of our proposed algorithm for chaotic modulation detection.

  • Preamble Design with HFMs for Underwater Acoustic Communications

    Hyperbolic frequency modulation (HFM) is Doppler insensitive. Therefore, HFM has been widely used in underwater acoustic communications as a preamble where wideband Doppler insensitivity is highly required. Based on this, we propose a new waveform named up-down-sweeping HFM (UMD-HFM). It combines an up-sweeping HFM and a down-sweeping HFM and leaves a span which is a little longer than delay spread of channel. UMD-HFM not only preserves the Doppler invariance, but also can be used to estimate the instantaneous Doppler scale for underwater communication. With this simple coding structure, UMD-HFM can also demonstrate a better detection performance.

  • MIMO underwater acoustic communications by using a quasi-orthogonal group space-time architecture

    Multiple-Input Multiple-Output (MIMO) systems have been widely applied to underwater acoustic (UWA) communications with promising results. However, the tradeoff between diversity and multiplexing gains in MIMO systems over underwater acoustic channel is less discussed. In this paper, a quasi- orthogonal group space-time (QoGST) scheme by combining space-time coding (STC) and layered space-time (LST) architecture is presented for better diversity and multiplexing gains in MIMO underwater acoustic communications. Simulation results show the presented solution has better performance when compared to the Group Layered Space-Time (GLST) scheme.

  • Ambiguities in underwater acoustic communications terminology and measurement procedures

    Well-defined terms and measurement procedures are important for transparency in communication and repro- ducibility of results.

This paper discusses a few important terms which are known to confuse people.

  • Long-Range Double-Differentially Coded Spread-Spectrum Acoustic Communications With a Towed Array

    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 that have been historically developed for radio- frequency terrestrial wireless communications, namely, direct sequence spread spectrum and double-differential coding. In DD-SS, direct sequence spread spectrum is employed to: 1) increase the signal-to-noise ratio; 2) suppress multipath interference; and 3) support data multiplexing, while double- differential coding makes reliable symbol recovery possible without explicit phase and Doppler tracking/correction. Thanks to the two techniques together with traditional beamforming, the DD-SS system is shown capable of effectively dealing with many challenging issues posed by LRAC with a towed HLA, without using complicated receiver processing. During the 2010 Long-Range Acoustic Communication Experiment (LRAC10) in deep waters, the DD-SS system was tested by using a moving source at a speed of 2-3 kn at 75-m depth and a 64-element HLA towed at 3.5 kn at a depth of 200 m. Excellent uncoded error performance (less than 4% bit error rate) is demonstrated at a data rate of 6.4 b/s for a bandwidth of 200 Hz and at a range of 550 km.

  • AoA based analysis of vector sensor receiver for underwater acoustic communications

    In this paper, we analyze a compact vector sensor receiver using angle of arrival (AoA) framework which was recently proposed by Fauziya et. al. We demonstrate that this receiver performs better than a scalar receiver at no extra computational cost. The receiver exploits the inherent capability of a vector sensor to provide spatial diversity without the use of a sensor array. The paper also discuss a compressive sensing based channel estimator that performs better than a least squares estimator. Channel estimation is performed using a training sequence and the simulation clearly bring out the superior performance of the compressive sensing based channel estimator and that of the vector sensor based compact receiver.

  • Soft Direct-Adaptive Turbo Equalization for MIMO underwater acoustic communications

    A Soft Direct-Adaptive Turbo Equalization (Soft DA-TEQ) is proposed for robust MIMO UWA communications. The proposed Soft DA-TEQ is derived under on the general frame of Expectation Maximization (E.M.) algorithm, which utilize the a priori soft decisions from the decoder to direct the equalizer's coefficients adaptation. The a priori soft decisions directed adaptation effectively lower the error propagation, which often cause catastrophic performance degradation in Hard DA-TEQ. Besides, in each iteration of the E.M. based soft adaption, the reliability of the symbol estimation is updated and used in the next iteration of soft adaption, which further enhances the convergence of the DA-TEQ. Experimental results show that the proposed Soft DA-TEQ is capable of robust detection in fast time varying MIMO UWA channels, even with low pilot overhead.

  • Towards Robust High Speed Underwater Acoustic Communications Using Chirp Multiplexing

    Wide band chirp spread spectrum (CSS) has been studied in underwater acoustic (UWA) communications to guarantee low bit error rates with low transmission rates. On the other hand, high speed transmission schemes for UWA, especially Orthogonal-Frequency-Division-Multiplexing (OFDM) technology, can reach Mbit/s data rates but at the expense of reliability. In this paper, we propose a new transmission scheme based on multiplexing information bits to (quasi-)orthogonal chirp signals, called Quasi-Orthogonal Chirp Multiplexing (QOCM). It can be easily implemented on reprogrammable hardware as an extension to OFDM architectures. We evaluated the performance of the proposed scheme with simulation and tank experiments. Results show that QOCM scheme is able to achieve one order of magnitude better performance than an OFDM scheme under severe Doppler effect posed by simulation in long distance water transmission. Moreover, we observe in water tank experiment that the QOCM scheme is resilient against to the Doppler effects induced by relative speeds up to 5 knots, which corresponds to a Doppler shift of 214.16 Hz at a center frequency of 125 kHz.
