Abstract:
A backscatter receiving module and a method of backscatter communication is described. A front-end module receives the backscatter signal from an antenna and generates high-speed and low-speed data. A high-speed decoding module outputs first data in response to the high-speed data having high-speed symbols that were encoded at a first frequency. The high-speed symbols include a first subset of symbols and a second subset of symbols. A low-speed decoding module outputs second data in response to receiving the low-speed data that was encoded into the backscatter signal at a second frequency. The low-speed decoding module generates a first state of the second data when the high-speed symbols of the high-speed data are in the first subset for a length of time. The low-speed module generates a second state of the second data when the high-speed symbols of the high-speed data are in the second subset for the length of time.
