Energy-Efficient MIMO Integrated Sensing and Communications With On–Off Nontransmission Power
This paper investigates the energy efficiency of a multiple-input multiple-output (MIMO) integrated sensing and communications (ISAC) system for Internet of things (IoT), in which one multi-antenna IoT transceiver transmits unified ISAC signals to a multi-antenna communication user (CU) and at the same time use the echo signals to estimate an …
