摘要
A method of non-coherent ambient backscatter communication including: receiving, by a wireless device, an ambient orthogonal frequency-division multiplexing (OFDM) symbol that includes a cyclic prefix at a first portion of the OFDM symbol that is a copy of a second portion of the OFDM symbol; modulating, by the wireless device, at least part of the received ambient OFDM symbol, including: modulating either the first portion or the second portion of the ambient OFDM symbol with data; and reflecting, by the wireless device, at least the first portion and the second portion of the modulated OFDM symbol.
