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

From the fourth generation (4G) of cellular systems onward, wireless personal devices (WPDs) support multi-input multi-output (MIMO) communication. However, impact MIMO communication on electromagnetic field (EMF) WPD users has yet to be fully understood and analyzed at system level. In this paper, we first provide a generic model for assessing individual exposure dose multi-antenna in multi-user multi-carrier system. An optimization framework minimizing is then developed based our model. This helps us identify new criterion, i.e., ratio between normalized channel noise (CNR), as main level criterion users. further integrated design two novel centralized resource allocation schemes that take advantage multiple antennas minimize per-user dose, when full or limited knowledge each user available. Our can significantly reduce (by approximately 80%) comparison with most relevant existing schemes. results also insights into logarithmic relationship number receive (or time slots), how such parameter exploited and/or higher SE while maintaining low dose.
