This book is concerned with integrated circuits and systems for wireless and
mobile communications. Circuit techniques and implementation of reconfigurable
low-voltage and low-power single-chip CMOS transceivers for multiband and multi-
mode universal wireless communications are the focus of the book. Applications
encompass both long-range mobile cellular communications (GSM and UMTS)
and short-range wireless LANs (IEEE802.11 and Bluetooth). Recent advances in
research into transceiver architecture, RF frontend, analogue baseband, RF CAD
and automatic testing are reported.
The challenges associated with the design and implementation of Electro-
static Discharge (ESD) protection circuits become increasingly complex as
technology is scaled well into nano-metric regime. One must understand the
behavior of semiconductor devices under very high current densities, high
temperature transients in order to surmount the nano-meter ESD challenge.
As a consequence, the quest for suitable ESD solution in a given technology
must start from the device level. Traditional approaches of ESD design may
not be adequate as the ESD damages occur at successively lower voltages in
nano-metric dimensions.
In order to enhance the efficiency and reliability of the power grid, diversify energy
resources, improve power security, and reduce greenhouse gas emission, many
countries have been putting great efforts in designing and constructing their smart
grid(SG) infrastructures.Smart gridcommunicationsnetwork(SGCN) is oneof the
key enabling technologies of the SG. However, a successful implementation of an
efficient and cost-effective SGCN is a challenging task

Software-defined radios (SDRs) have been around for more than a decade. The
first complete Global Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions. We therefore find it timely to publish an up-to-date text on the sub-
ject and at the same time include Galileo, the forthcoming European satellite-
based navigation system. Both GPS and Galileo belong to the category of Global
Navigation Satellite Systems (GNSS).
Human Factors and Systems Interaction aims to address the main issues of concern
within systems interface with a particular emphasis on the system lifecycle
development and implementation of interfaces and the general implications of
virtual, augmented and mixed reality with respect to human and technology
interaction. Human Factors and Systems Interaction is, in the first instance, affected
by the forces shaping the nature offuture computing and systems development
This texts contemporary approach focuses on the concepts of linear control systems, rather than computational mechanics. Straightforward coverage includes an integrated treatment of both classical and modern control system methods. The text emphasizes design with discussions of problem formulation, design criteria, physical constraints, several design methods, and implementation of compensators.Discussions of topics not found in other texts--such as pole placement, model matching and robust tracking--add to the texts cutting-edge presentation. Students will appreciate the applications and discussions of practical aspects, including the leading problem in developing block diagrams, noise, disturbances, and plant perturbations. State feedback and state estimators are designed using state variable equations and transfer functions, offering a comparison of the two approaches. The incorporation of MATLAB throughout the text helps students to avoid time-consuming computation and concentrate on control system design and analysis

Abstract Aim To propose a scheme for implementing FFT with FPGA in accor-dance with the
requirement for high speed digital signal processing. Methods The structure of FPGA and
requirement of system were considered in the experiment, radix-4 algorithm of DIT and recursive
structure were adopted. The group float point arithmetic operation was used in the butterfly and the
array multiplier was used to realize multiplication. Results The pipeline pattern was used to ensure
the system speed, it made fetching data, calculating twiddle factor, complex multiplication and D
