Digital Signal Processing with Examples in MATLAB®, Second Edition (Electrical Engineering & Applied Signal Processing Series) Review

Average Reviews:

(More customer reviews)I used this book for a first course on DSP. This book is very practical. It is loaded with Matlab algorithms that will make your discrete signal processing simulation development enjoyable and challenging.
The Matlab examples cover just about every thing encountered in DSP development. It covers statistical signal analysis, adaptive filter design, FIR, IIR and other important topics.
Readers of this book should download the entire code examples used in this book off the website assigned to this book.

Based on fundamental principles from mathematics, linear systems, and signal analysis, digital signal processing (DSP) algorithms are useful for extracting information from signals collected all around us. Combined with today's powerful computing capabilities, they can be used in a wide range of application areas, including engineering, communications, geophysics, computer science, information technology, medicine, and biometrics. Updated and expanded, Digital Signal Processing with Examples in MATLAB, Second Edition introduces the basic aspects of signal processing and presents the fundamentals of DSP. It also relates DSP to continuous signal processing, rather than treating it as an isolated operation.New to the Second EditionDiscussion of current DSP applications New chapters on analog systems models and pattern recognition using support vector machinesNew sections on the chirp z-transform, resampling, waveform reconstruction, discrete sine transform, and logarithmic and nonuniform sampling A more comprehensive table of transformsDeveloping the fundamentals of DSP from the ground up, this bestselling text continues to provide readers with a solid foundation for further work in most areas of signal processing. For novices, the authors review the basic mathematics required to understand DSP systems and offer a brief introduction to MATLAB. They also include end-of-chapter exercises that not only provide examples of the topics discussed, but also introduce topics and applications not covered in the chapters.

Femtocells: Technologies and Deployment Review

Average Reviews:

(More customer reviews)So what is a femtocell? It is a catchy name for a device "smaller" than a picocell [hence femto], that allows wireless access to a phone network and in practice also to the Internet. The book suggests that femtocells can play an important role in expanding wireless coverage to the interiors of buildings. Currently, basestations for mobile phones work best when the phones are outside. Once inside a building, the attenuation can be great enough so that contact is intermittent or non-existent. The crude workaround of having a basestation expand its power level is costly, both in terms of increasing interference with other basestations and also in the cost of the power. Plus, this still might not suffice to let a user inside a building get wireless contact.
The use of a femtocell inside a building is also reinforced by the expectation that this gadget will be bought and installed by an individual who lives there, or by a company who uses that building. This frees the cellular operator from the capital cost of supplying the femtocell. But as the book makes amply clear, a consequence is that femtocell setup, initialisation and maintenance needs to be as simple as possible; autonomic is the phrase used by the text. Readers might see the analogy with the popular use of DHCP for users with laptops who connect, wired or wirelessly, to the Internet. DHCP has greatly reduced the cognitive requirement on the users regarding low level technical settings.
A major issue in the book is how to handle handoffs when a mobile device moves between a femtocell and another femtocell or a macrocell [the latter is the regular cell around a basestation]. Several algorithms are proposed to optimise the change overs.

This book provides an in-depth guide to femtocell technologies

In this book, the authors provide a comprehensive and organized explanation of the femtocell concepts, architecture, air interface technologies, and challenging issues arising from the deployment of femtocells, such as interference, mobility management and self-organization. The book details a system level simulation based methodology addressing the key concerns of femtocell deployment such as interference between femto and macrocells, and the performance of both femto and macrocell layers. In addition, key research topics in interference modeling and mitigation, mobility management and Self-Organizing Network (SON) are highlighted. The authors also introduce HNB/HeNB standardization in 3GPP.. Furthermore, access methods (closed, open and hybrid), applications, timing synchronization, health issues, business models and security are discussed. The authors also provide a comparison between femtocells and other indoor coverage techniques such as picocells, repeaters, distributed antenna systems and radio over fiber. Lastly, both CDMA and OFDMA based femtocells are covered.

Key Features:

Provides a comprehensive reference on femtocells and related topics
Offers the latest research results on femtocells based on simulation and measurements
Gives an overview of indoor coverage techniques such as picocells, repeaters, distributed antenna systems, radio over fiber and femtocells
Includes chapters on femtocell access network architecture, air interface technologies (GSM, UMTS, HSPA, WiMAX and LTE), femtocell simulation, interference analysis and mitigation in femto/macrocell networks, mobility management in femto/macrocell networks, femtocell self-organization and other key challenges such as timing synchronization and security faced by femtocell deployment
Points to over 240 references from 3GPP, The Femto Forum, journals and conference proceedings

This book will be an invaluable guide for RF engineers from operators, R&D engineers from femtocells hardware manufacturers, employees from regulatory bodies, radio network planners, academics and researchers from universities and research organizations. Students undertaking wireless communications courses will also find this book insightful.
