Abstract-The fundamental tradeoff between the rates at which energy and reliable information can be transmitted over a single noisy line is studied. Engineering inspiration for this problem is provided by powerline communication, RFID systems, and covert packet timing systems as well as communication systems that scavenge received energy. A capacity-energy function is defined and a coding theorem is given. The capacity-energy function is a non-increasing concave ∩ function. Capacity-energy functions for several channels are computed.
SWIPT was firstly introduced in REF , where information and energy are transmitted over a single noisy line and the tradeoff between data rate and energy are studied.
