On the Exposure Dose Minimization of Multi-Antenna Multi-Carrier System Users

Abstract: From the fourth generation (4G) of cellular systems onward, wireless personal devices (WPDs) support multi-input multi-output (MIMO) communication. However, the impact of MIMO communication on the electromagnetic field (EMF) of WPD users has yet to be fully understood and analyzed at the system level. In this paper, we first provide a generic model for assessing the individual exposure dose of multi-antenna WPD users in a multi-user multi-carrier communication system. An optimization framework for minimizing t… Show more

“…They propose an optimization strategy to select the RIS phases to minimize the EMF exposure in terms of the exposure index while maintaining a minimum target QoS for the users. The authors of [29] propose an optimization strategy to minimize the average exposure dose of users, considering both the system's QoS and transmit power constraints. Given that our resource allocation scheme maximizes the minimum user SINR, we must ensure that the resulting solution will not result in users experiencing more EMF radiation than the stipulated thresholds.…”

“…In uplink transmissions, EM exposure is measured by a standard metric named specific absorption rate (SAR), which indicates the EM power absorbed by human tissue per unit mass [3]. Compared with the constraint on power, which is only related to the amplitudes of multiple antennas, SAR is also the function of phase differences between any two transmit signals [7], [8]. The SAR model is based on experimental studies, which can be characterized by the sinusoidal function of the phase difference [9].…”
