Reconstruction- and example-based super-resolution
(SR) methods are promising for restoring a high-resolution
(HR) image from low-resolution (LR) image(s). Under large
magnification, reconstruction-based methods usually fail
to hallucinate visual details while example-based methods
sometimes introduce unexpected details. Given a generic
LR image, to reconstruct a photo-realistic SR image and
to suppress artifacts in the reconstructed SR image, we
introduce a multi-scale dictionary to a novel SR method
that simultaneously integrates local and non-local priors.
The local prior suppresses artifacts by using steering kernel regression to predict the target pixel from a small local
area. The non-local prior enriches visual details by taking
a weighted average of a large neighborhood as an estimate
of the target pixel. Essentially, these two priors are complementary to each other. Experimental results demonstrate
that the Proposed method can produce high quality SR recovery both quantitatively and perceptually.

Relaying techniques, in which a source node communicates to a destination node
with the help of a relay, have been Proposed as a cost-effective solution to address
the increasing demand for high data rates and reliable services over the air. As
such, it is crucial to design relay systems that are able to not only provide high
spectral efficiency, but also fully exploit the diversity of the relay channel.

Optical communication technology has been extensively developed over the
last 50 years, since the Proposed idea by Kao and Hockham [1]. However, only
during the last 15 years have the concepts of communication foundation, that
is, the modulation and demodulation techniques, been applied. This is pos-
sible due to processing signals using real and imaginary components in the
baseband in the digital domain. The baseband signals can be recovered from
the optical passband region using polarization and phase diversity tech-
niques, as well as technology that was developed in the mid-1980s.

Thisbookfocusesontheemergingresearchtopic‘green(energy-efficient)wirelessnetworks’
that has drawn huge attention recently from both academia and industry. This topic is highly
motivated due to important environmental, financial and quality-of-experience (QoE) consid-
erations.Duetosuchconcerns,varioussolutionshavebeenProposedtoenableefficientenergy
usage in wireless networks, and these approaches are referred to as green wireless communi-
cations and networking. The term ‘green’ emphasizes the environmental dimension of the
Proposed solutions. Hence, it is not sufficient to present a cost-effective solution unless it is
eco-friendly.

This research work aims at eliminating the off-chip RF SAW filters from fre-
quency division duplexed (FDD) receivers. In the first approach, a monolithic passive
RF filter was constructed using on-chip capacitors and bondwire inductors. The bond-
wire characteristics were studied in details and the effect of mutual inductive coupling
between the bondwires on the filter performance was analyzed. Based on that, a bond-
wire configuration was Proposed to improve the frequency response of the filter. The
filter was implemented in 0.18 μm CMOS process for WCDMA applications.

Since the principle of multi-carrier code division multiple access (MC-CDMA) was
simultaneously Proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE
International Symposium on Personal, Indoor and Mobile Radio Communications
(PIMRC) in the year 1993, multi-carrier spread spectrum (MC-SS) has rapidly become
one of the most wide spread independent research topics on the field of mobile radio
communications. Therefore, the International Workshop on Multi-Carrier Spread
Spectrum (MC-SS) was initiated in the year 1997. Multi-carrier and spread spectrum
systems with their generic air interface and adaptive technologies are considered as
potential candidates to fulfill the requirements of next generation mobile communications
systems.

The author’s group has developed various chipless RFID tags and reader architectures
at 2.45, 4–8, 24, and 60 GHz. These results were published extensively in the form of
books, book chapters, refereed conference and journal articles, and finally, as patent
applications. However, there is still room for improvement of chipless RFID sys-
tems. In this book, we Proposed advanced techniques of chipless RFID systems that
supersede their predecessors in signal processing, tag design, and reader architecture.

Since OpenStreetMap (OSM) appeared more than ten years ago, new
collaborative mapping approaches have emerged in different areas and have become
important components of localised information and services based on localisation.
There is now increased awareness of the importance of the space-time attributes of
almost every event and phenomenon. Citizens now have endless possibilities to
quickly geographically locate themselves with an accuracy previously thought
impossible. Based on these societal drivers, we Proposed a number of collaborative
mapping experiments (“mapping parties”) to delegates of a large open-source
geospatial conference and to citizens of the conference’s host city during July 2015.
