This SpringerBrief explores the advantage of relaying techniques in
addressing the increasing demand for high data rates and reliable
services over the air. It demonstrates how to design cost-effective
relay systems that provide high spectral efficiency and fully exploit
the diversity of the relay channel. The brief covers advances in
achievable rates, power allocation schemes, and error performance for
half-duplex (HD) and full-duplex (FD) amplify-and-forward (AF)
single-relay systems. The authors discuss the capacity and respective
optimal power allocation for a wide range of HD protocols over static
and fading channels. Then, optimal amplification coefficients in terms
of achievable rate are presented. Chapters also examine performance with
finite constellations, including the error and diversity performance.
The brief concludes with a capacity and error performance analysis of
the FD relay mode of operation, where the residual self-interference due
to FD transmission is explicitly taken into account. Amplify-and-Forward
Relaying in Wireless Communications reveals the benefits and challenges
of relaying techniques. It is designed for researchers and professionals
in wireless communication. This material is also appropriate for
advanced-level students in electrical engineering and computer science.
