Research in information, communications and signal processing has
brought about new services, applications and functions in a large
number of fields which include consumer electronics, biomedical
devices and defence. These applications play an important role in
advancing technologies to enhance human life in general. Recent
Advances in Information, Communications and Signal Processing aims
to give students, researchers, and engineers information pertaining
to recent advances in these fields. In terms of research in signal
processing topics, the two chapters included in this book have a
strong emphasis on advances in algorithmic development in the
biomedical, and human-computer interfaces domain areas. More
specifically, the use of deep learning for placental maturity
staging is discussed as well as the use of vibration analysis for
localising impacts on surfaces for human-computer applications. In
terms of communications signal processing, advances in new wireless
communication such as NOMA (non-orthogonal multiple access) and
millimetre-wave antenna design for 5G cellular mobile radio, as
well as innovations in LDPC (low density parity check code)
decoding and networking coding, are featured.
Space-time block code (STBC) is a maturing technology to achieve
transmit diversity over fading channels. As the number of transmit
antennas increases beyond two, current approaches to design STBCs
either make trade off between the achievable diversity gain and the
code rate, or achieve both full diversity and full rate at the
expense of exponentially increased decoder complexity. This book
presents a new STBC design method that combines two real orthogonal
STBCs (O-STBC) with offset QAM. This approach is able to achieve
both full diversity and full code rate, yet allows simple real
symbol wise decoding whose complexity is independent of the number
of transmit antennas. This book provides a detailed analysis of the
impact of key system parameters on the error performance of the
scheme. A complete chapter is devoted to systematic design of the
two real O-STBCs for optimal error performance. This book should be
useful to any researcher who is in the field of MIMO
communications, or any engineering professional who is looking for
an effective STBC solution for practical implementation.
