Embodiment Construction
[0042] The present invention will be further described below in conjunction with the accompanying drawings.
[0043] refer to Figure 1 ~ Figure 3 , a wireless energy-carrying communication method based on orthogonal frequency division multiplexing amplification and forwarding two-way cooperation, which is realized based on an existing wireless communication system, and the wireless energy-carrying communication system consists of a source node S 1 , S 2 and relay nodes R, S 1 → R link and S 2 → The entire bandwidth of the R link is divided into K subcarriers, and the transmission time is divided into two equal time slots.
[0044] In this embodiment, in the first time slot, the source node S 1 and S 2 Send information to the relay node R, the relay node uses a part of the subcarriers to receive the signal, and uses the rest of the subcarriers to collect energy; in the second time slot, the relay node uses the collected energy to perform subcarrier pairing, and then ampli...
