In this paper, we investigate the performance of cache-assisted simultaneous wireless information and power transfer (SWIPT) cooperative systems, in which one source communicates with one destination via the aid of multiple relays. In order to prolong the relays' serving time, the relays are assumed to be equipped with a cache memory and energy harvesting (EH) capability. Based on the time-splitti...
