Abstract
A method for preserving a frame check sequence (FCS) of a data frame during backscatter communication is provided. The method comprises: receiving a transmitted signal including a transmitted data frame, wherein the transmitted data frame includes a first data sequence and the FCS; determining a cyclic redundancy check (CRC) preservation sequence based on a backscattering tag data sequence, a bit-length of the backscattering tag data sequence, and a given CRC algorithm; and backscattering the transmitted signal to form a backscattered signal including a backscattered data frame, wherein the backscattered data frame includes a second data sequence and the FCS. The second data sequence includes a transmitted data sequence, an encoded tag data sequence and the CRC preservation sequence. The CRC preservation sequence preserves the FCS of the transmitted data frame in the backscattered data frame. The FCS is usable to detect communication errors in the backscattered data frame.
