5G Physical Layer: Principles, Models and Technology Components
explains fundamental physical layer design principles, models and
components for the 5G new radio access technology - 5G New Radio
(NR). The physical layer models include radio wave propagation and
hardware impairments for the full range of frequencies considered
for the 5G NR (up to 100 GHz). The physical layer technologies
include flexible multi-carrier waveforms, advanced multi-antenna
solutions, and channel coding schemes for a wide range of services,
deployments, and frequencies envisioned for 5G and beyond. A
MATLAB-based link level simulator is included to explore various
design options. 5G Physical Layer is very suitable for wireless
system designers and researchers: basic understanding of
communication theory and signal processing is assumed, but
familiarity with 4G and 5G standards is not required. With this
book the reader will learn: The fundamentals of the 5G NR physical
layer (waveform, modulation, numerology, channel codes, and
multi-antenna schemes). Why certain PHY technologies have been
adopted for the 5G NR. The fundamental physical limitations imposed
by radio wave propagation and hardware impairments. How the
fundamental 5G NR physical layer functionalities (e.g.,
parameters/methods/schemes) should be realized. The content
includes: A global view of 5G development - concept,
standardization, spectrum allocation, use cases and requirements,
trials, and future commercial deployments. The fundamentals behind
the 5G NR physical layer specification in 3GPP. Radio wave
propagation and channel modeling for 5G and beyond. Modeling of
hardware impairments for future base stations and devices. Flexible
multi-carrier waveforms, multi-antenna solutions, and channel
coding schemes for 5G and beyond. A simulator including hardware
impairments, radio propagation, and various waveforms. Ali Zaidi is
a strategic product manager at Ericsson, Sweden. Fredrik Athley is

This book describes algorithmic methods and parallelization
techniques to design a parallel sparse direct solver which is
specifically targeted at integrated circuit simulation problems.
The authors describe a complete flow and detailed parallel
algorithms of the sparse direct solver. They also show how to
improve the performance by simple but effective numerical
techniques. The sparse direct solver techniques described can be
applied to any SPICE-like integrated circuit simulator and have
been proven to be high-performance in actual circuit simulation.
Readers will benefit from the state-of-the-art parallel integrated
circuit simulation techniques described in this book, especially
the latest parallel sparse matrix solution techniques.
This thesis introduces novel and significant results regarding the
analysis and synthesis of positive systems, especially under l1 and
L1 performance. It describes stability analysis, controller
synthesis, and bounding positivity-preserving observer and
filtering design for a variety of both discrete and continuous
positive systems. It subsequently derives computationally efficient
solutions based on linear programming in terms of matrix
inequalities, as well as a number of analytical solutions obtained
for special cases. The thesis applies a range of novel approaches
and fundamental techniques to the further study of positive
systems, thus contributing significantly to the theory of positive
systems, a "hot topic" in the field of control.

Reliable video communications over error-prone networks has been a
very challenging task. During video transmission, packet losses may
occur due to channel errors, especially over those relatively
unreliable networks, e.g. wireless networks. In many real-time
applications, the retransmission of video data is not feasible
because of the application natures. Thus, it is important to
develop approaches to recover the lost video data and "conceal" the
errors when packet losses occur. This book (thesis) provides a
comprehensive study on "error concealment" techniques employed in
modern video communication systems, and proposes new approaches to
this field as well as extensive evaluation results.
This book focuses on the convergence of energy, communication and
computation in the beyond 5G (B5G) cellular Internet of Things
(IoT). It addresses both theory and techniques, with more weight
placed on the latter. This is achieved by providing in-depth
studies on a number of major topics such as wireless power
transfer, non-orthogonal multiple access, massive multiple-input
multiple-output, and over-air computation. In turn, four typical
convergence scenarios are studied in detail: the convergence of
energy and communication, convergence of energy and computation,
convergence of communication and computation, and convergence of
energy, communication and computation. The comprehensive and
systematic coverage of key techniques in the convergence of energy,
communication and computation in the B5G cellular IoT is one of the
book's major features, making it particularly well suited for
readers who are interested in learning about practical solutions in
B5G wireless networks. Accordingly, the book offers a valuable
resource for researchers, engineers, and graduate students in the
fields of information engineering, telecommunications engineering,
computer engineering, etc.
