AI Technical Summary
Technical Problem
The AMP single-station back reflection has a serious self-interference problem, which affects the communication effect.
Method used
By modulating square wave signals with different period values in the information bitstream, their spectra are shifted to different frequency positions to avoid self-interference, and the information bitstream is demodulated through simple spectrum detection.
Benefits of technology
It effectively solves the self-interference problem in AMP single-station back reflection, reduces the probability of clock synchronization failure, and improves the reliability and efficiency of communication.

Abstract
Provided in the present application are a communication method, a communication apparatus, and a communication system. In the method, since a first bit value and a second bit value in an information bit stream are both modulated into square wave signals, the spectrum of a carrier signal corresponding to the first bit value is shifted, relative to the spectrum of a first carrier signal, by a shift distance of the reciprocal of a first period (i.e., a first frequency), and the spectrum of a carrier signal corresponding to the second bit value is also shifted, relative to the spectrum of the first carrier signal, by a shift distance of the reciprocal of a second period (i.e., a second frequency). Since the spectra of the carrier signals corresponding to the bit values (i.e., the first bit value and the second bit value) in the information bit stream are shifted relative to the spectrum of the first carrier signal, the mutual interference between the first carrier signal and the second carrier signal is avoided, thereby solving the problem of AMP mono-static backscatter being subjected to severe self-interference.
