Review Article: Multicarrier Communication for Underwater Acoustic Channel
In past decades, there has been a growing interest in the discussion and study of using underwater acoustic channel as the physical layer for communication systems, ranging from point-to-point communications to underwater multicarrier modulation networks. A series of review papers were already available to provide a history of the development of the field until the end of the last decade. In th...
متن کاملSub-space Channel Tracking for Correlated Underwater Acoustic Communication Channels
Many underwater acoustic channels exhibit correlated (semideterministic) multipath arrivals. Such channels are often timevarying with extensive multipath delay and yet have a limited number of degrees of freedom due to inter-path correlation. Traditional channel estimation algorithms do not exploit this correlation structure. To exploit cross-tap correlation, the channel impulse response is pro...
متن کاملAdaptive and efficient nonlinear channel equalization for underwater acoustic communication
We investigate underwater acoustic (UWA) channel equalization and introduce hierarchical and adaptive nonlinear channel equalization algorithms that are highly efficient and provide significantly improved bit error rate (BER) performance. Due to the high complexity of nonlinear equalizers and poor performance of linear ones, to equalize highly difficult underwater acoustic channels, we employ p...
متن کاملAdaptive Channel Estimation for Multiuser Underwater Communication Systems
Problem statement: Multiple Access Interference (MAI) signals and poor estimation of the unknown channel parameters in the presence of limited training sequences are two of the major problems that degrade the systems’ performance. Two synchronous multiuser receivers with Rake reception of Interleave Division Multiple Access (IDMA) and Code Division Multiple Access (CDMA) systems, in conjunction...
متن کاملdesign and simulation study of a short range underwater communication system employing a novel model for shallow water multipath acoustic channel in the persian gulf
in this paper, for the purpose of investigating horizontal sound propagation, based on the results obtained from practical measurements in the strait of hormoz and available data on sound speed variations at different depths, a comprehensive model for shallow water multipath underwater acoustic channel is presented. mathematical modeling of multipath effect is based on ray theory and the image ...
