Ambient backscattering communication system, associated apparatus and method

A method for optimizing ambient backscattering communication in an ambient backscattering communication system comprising:

• an ambient backscattering transmitter suitable for generating an ambient backscattering signal according to a first polarization from an ambient signal incident on the transmitter,
• an ambient backscattering receiver suitable for detecting the ambient backscattering signal transmitted by the ambient backscattering transmitter according to a second polarization, and
• a reduction device for reducing the interference between the ambient backscattering signal and an ambient signal incident on the receiver, the reduction device controlling the first polarization and the second polarization
• at least one of said first and second polarizations being adjustable,
• the method comprising at least one step of:
• varying the first polarization and the second polarization so that the value of a performance criterion of the communication system is optimized, the criterion being selected from the group consisting of error rate, throughput, transmission time, signal-to-noise ratio and interference, and quality of service.
