摘要： Disclosed are a communication method and communication apparatus using an ambient backscatter communication. A transmission apparatus may include generating a plurality of bitsets by fragmenting data based on a predetermined bitset length, mapping the plurality of bitsets to a plurality of switching patterns based on a data size, and controlling a reflection of a background radio frequency (RF) signal based on a corresponding mapped switching pattern, a total number of the plurality of switching patterns may be determined based on the bitset length, and each of the plurality of switching patterns may have a different length.

摘要： A backscatter communication method and apparatus based on pattern-based demodulation is disclosed. The backscatter communication method includes receiving a communication signal, and demodulating the communication signal based on a slope of the communication signal at an edge of each time interval.
