Underwater voice communications using digital techniques
نویسندگان
چکیده
A digital signal processor (DSP) based voice communication system for divers with a 2400 bitls transmission rate is described. Each speech signal frame is analysed using linear predictive coding (LPC) and the essential parameters such as amplitude, pitch period and digital filter coefficients are extracted. These parameters are transmitted through a water channel at a rate of 2400 bitls by employing digital pulse position.modulation (DPPM).

Underwater Acoustic Voice Communications Using Digital Pulse Position Modulation
The paper presents a novel technique for underwater acoustic voice communications. The speech signal is compressed prior to transmission by using Linear Predictive Coding and transmission of appropriate speech parameters is achieved by Digital Pulse Position Modulation. The main emphasis here is on the reception of the multipath-dominant signal and on the demodulation process.
متن کاملOn the Practical Aspects of Joint Passive Phase Conjugation and Equalization Underwater Communication Systems
Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...

A high bit rate acoustic link over an underwater channel is investigated . Design of a Digital communication system utilizing acoustic signals for underwater applications is a very challenging field due to the extremely complex nature of the underwater channel. The conventional techniques for overcoming the channel effects used in communication systems elsewhere fail to give the desired results...
متن کاملIterative Equalization and Decoding Scheme for Underwater Acoustic Coherent Communications
Digital communications through underwater acoustic (UWA) channels differ from those in other media, such as radio channels, due to the high temporal and spatial variability of the acoustic channel which make the available bandwidth of the channel limited and dependent on both range and frequency. In order to overcome disadvantage factors and maximize performance to conduct real-time information...
متن کاملVery Low Rate Speech Coding Algorithm Based on Biomimetic Pattern Recognition ⋆
Based on the speech coding technology, in this paper we propose a new method encoding the speech signal by the bionic pattern recognition technique. Using this new encoding method, the text message can be received after using biomimetic pattern recognition of the speaker’s voice. And the information related to the speaker’s individual characteristics can be obtained by “comparison” between the ...
