Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] refer to Figure 1 ~ Figure 3 , a wireless energy-carrying communication method based on OFDM subcarrier allocation is implemented based on an existing wireless communication system, and the wireless energy-carrying communication system is composed of a pair of transmitting end (Tx) and receiving end (Rx), and the transmitting There are K subcarriers at the end.

[0036] In the method of this embodiment, the sending end sends information to the receiving end, and the receiving end uses a part of subcarriers to receive the information according to the channel state. If the received information rate R is greater than the target rate, that is, R≥R T , the remaining subcarriers are used to harvest energy.

[0037] In this embodiment, the information rate R received by the receiving end and the collected energy Q can be obtained by the following methods:

Abstract

The invention discloses a wireless energy carrying communication method based on OFDM sub-carrier allocation. According to the method, a receiving end employs part of sub-carriers to receive information according to a channel state, and the rest sub-carriers in a field of vision are used for collecting energy. The receiving end only needs to know which sub-carriers are used for receiving information, and which sub-carriers are used for receiving the energy, namely, the receiving end only needs to know sub-carrier serial numbers for receiving the information and receiving the energy. An allocator is unnecessarily added at the receiving end. According to the method, the design complexity of the receiving end is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless energy-carrying communication in the field of wireless communication, in particular to an energy-carrying communication method. Background technique [0002] In recent years, the business demands of wireless communication systems have been increasing day by day, and the amount of data has grown exponentially. In addition to the urgent situation of wireless spectrum resources, people are also faced with the challenge of excessive consumption of energy resources. With the rapid development of science and technology, interdisciplinary and multi-platform integration and integration have gradually become an important trend of technological innovation and the source of power for industrial progress. Sustainable scientific development urgently needs to integrate the existing research results of current communication technology and energy technology. To meet people's needs for efficient and reliable info...
