Future wireless networks are expected to constitute a distributed intelligent wireless communications, sensing, and computing platform, which will have the challenging requirement of interconnecting the physical and digital worlds in a seamless and sustainable manner. Currently, two main factors prevent wireless network operators from building such networks: (1) the lack of control of the wireless...
A wise resource allocation design for a wireless network allows the optimization of a number of relevant parameters such as the data-rate, the radiated power, the number of supported users, and so on. Among these parameters, we focus on the energy-efficiency [1,2,3, and references therein], defined here as the number of error-free delivered bits for each energy-unit used for transmission.
Resource allocation for energy efficiency optimization in multi-carrier interference networks with multiple receive antennas is tackled. First, a one-hop network is considered, and then, the results are extended to the case of a two-hop network in which amplify-and-forward relaying is employed to enable communication. A distributed algorithm which optimizes a system-wide energy-efficient performance...
