The present time is a period of rapid development of electronic and information technologies. It is accompanied by lowered costs in the production and implementation of these technologies. Thanks to this, they can be used in devices where advanced control has not been used so far. An example of such devices are, e.g., electric tools. The use of modern electronics can reduce the dimensions of devices, increase their reliability and reduce energy consumption. Advanced control algorithms can have a positive impact on the safety of people's work and reliability of devices. The use of complex electronics, software, and algorithms is a big challenge for the designers of these systems.
Recently, massive MIMO (mMIMO) has emerged as a key technology for the upcoming fifth-generation (5G) wireless networks. In fact, mMIMO and millimeter waves (mmWaves) have been identified as critical technologies to improve transmission rate and energy efficiency in 5G mobile communication systems. Due to the large propagation attenuation, mmWaves may present some additional advantages regarding frequency reuse, user support, and communication security but also makes energy efficiency more critical. In fact, energy efficiency (EE) is a critical issue when considering circuit power consumption (CPC) in fifth-generation cellular networks. These efficiency problems arise with the increasing number of antennas in mMIMO systems, attributable to a higher number of radio frequency (RF) chains at the base station that consume more power due to the processing activities in digital-to-analogue converters and power amplifiers. In addition, low latency and energy efficiency make complexity a critical issue in mMIMO systems. Thus, energy-efficient physical layer solutions may be critical to assure good trade-offs between complexity and energy efficiency.
This Special Issue is dedicated to energy efficiency in massive MIMO systems and Antenna wave propagation with an emphasis on energy and low complexity physical layer security solutions suited for these systems. Therefore, researchers are invited to submit their manuscripts to this Special Issue and contribute their models, proposals, reviews, and studies.
