Описание: Field-Programmable Gate Arrays (FPGAs) are revolutionizing digital signal processing as novel FPGA families are replacing ASICs and PDSPs for front-end digital signal processing algorithms. So the efficient implementation of these algorithms is critical and is the main goal of this book. It starts with an overview of today's FPGA technology, devices, and tools for designing state-of-the-art DSP systems. A case study in the first chapter is the basis for more than 40 design examples throughout. The following chapters deal with computer arithmetic concepts, theory and the implementation of FIR and IIR filters, multirate digital signal processing systems, DFT and FFT algorithms, advanced algorithms with high future potential, and adaptive filters. Each chapter contains exercises. The VERILOG source code and a glossary are given in the appendices, while the accompanying CD-ROM contains the examples in VHDL and Verilog code as well as the newest Altera "Quartus II web edition" software. This edition has a new chapter on microprocessors, new sections on special functions using MAC calls, intellectual property core design and arbitrary sampling rate converters, and over 100 new exercises.

Описание:
Following underwater acoustic channel modeling, this book investigates the relationship between coherence time and transmission distances. It considers the power allocation issues of two typical transmission scenarios, namely short-range transmission and medium-long range transmission. For the former scenario, an adaptive system is developed based on instantaneous channel state information. The primary focus is on cooperative dual-hop orthogonal frequency division multiplexing (OFDM).
This book includes the decomposed fountain codes designed to enable reliable communications with higher energy efficiency. It covers the Doppler Effect, which improves packet transmission reliability for effective low-complexity mirror-mapping-based intercarrier interference cancellation schemes capable of suppressing the intercarrier interference power level.
Designed for professionals and researchers in the field of underwater acoustic communications, this book is also suitable for advanced-level students in electrical engineering or computer science.

Описание: This volume constitutes the results of the International Conference onUnderwater Environment, MOQESM’14, held at “Le Quartz” Conference Center in Brest,France, on October 14-15, 2014, within the framework of the 9thSea Tech Week, International Marine Science andTechnology Event. The objective of MOQESM'14 was to bring together researchers fromboth academia and industry, interested in marine robotics and hydrography withapplication to the coastal environment mapping and underwater infrastructuressurveys.The common thread of the conference is the combination of technicalcontrol, perception, and localization, typically used in robotics, with the methods of mappingand bathymetry.The papers presented in this book focus on two main topics.Firstly, coastal and infrastructure mapping is addressed, focusing notonly on hydrographic systems, but also on positioning systems, bathymetry, and remote sensing. Theproposed methods rely on acoustic sensors such as side scan sonars, multibeam echo sounders,phase-measuring bathymetric sonars, as well as optical systems such as underwater laser scanners.Accurate underwater positioning is also addressed in the case of the use of a singleacoustic beacon, and the latest advances in increasing the vertical precision of Global NavigationSatellite System (GNSS) are also presented.Most of the above mentioned works are closely related to autonomousmarine vehicles. Consequently, the second part of the book describes some works concerning the methodsassociated with such type of vehicles. The selected papers focus on autonomous surface orunderwater vehicles, detailing new approaches for localization, modeling, control, mapping, obstacledetection and avoidance, surfacing, and software development. Some of these works imply acoustics sensing aswell as image processing. Set membership methods are also used in some papers.The applications of the work presented in this book concern inparticular oceanography, monitoring of oil and gas infrastructures, and military field.

Описание: This second edition provides comprehensive information on electromagnetic acoustic transducers (EMATs), from the theory and physical principles of EMATs to the construction of systems and their applications to scientific and industrial ultrasonic measurements on materials. The original version has been complemented with selected ideas on ultrasonic measurement that have emerged since the first edition was released. The book is divided into four parts:PART I offers a self-contained description of the basic elements of coupling mechanisms along with the practical designing of EMATs for various purposes. Several implementations to compensate for EMATs’ low transfer efficiency are provided, along with useful tips on how to make an EMAT.PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of EMATs’ contactless nature and is the most successful amplification mechanism for precise measurements of velocity and attenuation.PART III applies EMAR to studying physical acoustics. New measurements have emerged with regard to four major subjects: in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, pointwise elasticity mapping (RUM), and acoustic nonlinearity evolution.PART IV deals with a variety of individual issues encountered in industrial applications, for which the EMATs are believed to be the best solutions. This is proven by a number of field applications.
