1. An ambient backscattering communication system, the 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,
and wherein at least one of said first and second polarizations is adjustable.
