Frequency-Domain Receiver Design for Doubly-Selective Channels discusses broadband wireless transmission techniques, which are serious candidates to be implemented in future broadband wireless and cellular systems, aiming at providing high and reliable data transmission and concomitantly high mobility. This book provides an overview of the channel impairments that may affect performance of single carrier and multi-carrier block transmission techniques in mobile environments. Moreover, it also provides a new insight into the new receiver designs able to cope with double selectivity that affects present and future broadband high speed mobile communication systems.
"The book presents a strong analytical rigor and very interesting solutions to some of the most important challenges that wireless communication engineers face. All the analytical derivations and innovative results are well supported by a large set of figures which turns the book a very useful tool. It also presents an important revision of existing techniques, which clearly enrich its quality."

"The book covers a timely and important topic for current and future wireless communication systems." — Imad Barhumi, United Arab Emirates University, Al Ain, Abu Dhabi
"Advanced receiver designs for frequency selective channels was, from the beginning, a disruptive idea which opened horizons to up-until-then unimaginable data rates and system capacities in wireless systems. This book offers a fresh look at receiver designs, and looks at its combination with SC-FDE and OFDM, and the impact at the system-level. Receiver designs remains a pillar of high-speed systems beyond 4G which incorporate massive MIMO and network coding at the physical layer."
—Mário Marques da Silva, Universidade Autónoma de Lisboa, Portugal
"There are not many books addressing the treatment of Doubly Selective Channels, and none devoted especially to the design of frequency domain receivers….this book appears to treat both block based single carrier and multicarrier communications, comparing them both in detail, on the contrary of most books devoted to multicarrier, with special emphasis on OFDM, although the growing importance of SC-FDE for uplink transmissions. This book seems to fill this void, providing a current view on the state-of-the-art."
— Marco Alexandre Cravo Gomes, University of Coimbra, Portugal
"This book addresses the state of the art in OFDM and SC-FDE bock transmission schemes. It includes an easy to read overview accompanied by a formal definition of the block transmission schemes and channels models. The most interesting parts cover advanced analytical tools for channel estimation and receiver design for asynchronous networks and for multipath channels with strong Doppler effects. Asynchronous access is envisioned in the transmission schemes for future 5G systems. On the other end, Doppler effects are gaining importance as higher carrier frequencies and broader bands are used. Given the tutorial presentation, these physical layer models can be quite helpful in the design and analysis of cross-layer optimized systems."
—Luis Bernardo, Instituto de Telecomunicações, Lisbon, Portugal
"Frequency-Domain Receiver Design for Doubly Selective Channels summarizes extensive research work on wireless communication between OFDM and SC-FDE and suggests the optimum approach. In so doing, it might revolutionize wireless communication technology."
