Adaptive multichannel combining and equalization for underwater acoustic communications
A theoretically optimal multichannel receiver for intersymbol interference communication channels is derived, and its suboptimal versions with linear and decision feedback equalizer are presented. A practical receiver based on any of these structures encounters difficulties in the underwater acoustic channels in which the extended time-varying multipath is accompanied by phase instabilities. A ...
متن کاملAdaptive MMSE turbo equalization with high-order modulations and spatial diversity applied to underwater acoustic communications
This paper presents some results on adaptive minimum mean-square error (MMSE) turbo equalization obtained from underwater experiments in the Atlantic ocean. The performance gain is evaluated as a function of the number of hydrophones at the receiver side. Single-carrier transmission with high-order modulations is considered, at a coded bit rate as high as 24 kb/s on the underwater acoustic chan...
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 Underwater Acoustic Communications
Underwater wireless networks consist of mobile and static nodes, which usually communicate using the acoustic channel since radio transmissions attenuate rapidly and optical communication is only suitable for short distances. The underwater acoustic channel is plagued with issues of high transmission power requirements, rapidly changing channel characteristics, multi-path echoes, possible high ...
متن کاملImprovement of Multiple-input/multiple-output Time Reversal Communications in Underwater Acoustic Channels Using Adaptive Equalizers
The spatial and temporal focusing properties of time reversal methods can be exploited for undersea acoustic communications. Spatial focusing mitigates channel fading and produces a high signal-to-noise ratio at the intended receivers along with a low probability of interception elsewhere. While the temporal focusing (compression) reduces significantly intersymbol interference (ISI), there alwa...
