This letter investigates a cognitive wireless powered communication (WPC) system coexisting with a primary wireless communication system, in which a cognitive or secondary wireless device (S-WD) uses its harvested energy from a multi-antenna secondary hybrid access point (S-HAP) and the primary transmitter to communicate with the S-HAP. Based on the channel conditions at each fading state, the cognitive WPC system can adaptively switch the transmission mode between the forward-link energy… CONTINUE READING
