Abstract
Energy‐constrained wireless networks, such as sensor networks, are typically powered by batteries that have limited operation time. This chapter focuses on the downlink case with simultaneous wireless information and power transfer (SWIPT) from the access point (AP) to user terminals (UTs). It considers simplified scenarios with only one or two active UTs in the network. The chapter analyzes the multi‐antenna design for rate‐energy region characterization in a two‐user SWIPT system with separated information decoding (ID) receiver and energy harvesting (EH) receivers, by assuming perfect channel state information (CSI) at the transmitter. It reveals fundamental trade‐offs in designing wireless MIMO systems for maximizing the efficiency of simultaneous information and energy transmission and discusses some extensions of such a SWIPT design to different setups by considering various practical considerations.
