"Advanced Relay Technologies in Next Generation Wireless Communications" describes the use of the highly successful cooperative networks/relaying approach in new and emerging telecommunications technologies such as full-duplex radio, massive multiple-input multiple-output (MIMO), network coding and spatial modulation, and new application areas including visible light communications (VLC), molecular communications, wireless power transfer, and 5G.Topics covered include: -spatial modulation for cooperative networks-relaying for massive MIMO; relaying for outdoor to indoor in mmWave communications-precoding techniques for relaying with interference-relaying in full-duplex radio communication systems-relay selection in modern communication systems-relaying in green communications systems-energy-efficient relaying-cognitive radio with relaying-relaying in non-ideal conditions-relaying and physical layer secrecy relaying technologies for smart grid-simultaneous wireless and power transfer for interference relay channel-relaying in visible light communication systems-on-ground and on-board signal processing for multibeam precoding.
