Abstract (en)
[origin: WO2021224563A1] The invention relates to a control device (D_CO) for controlling the operation of a wireless communication device (D_TX) comprising an antenna (100), a front-end module configured for transmitting and receiving signals according to a frequency-division multiplexing scheme, and switching means (110) capable of configuring at least one transmission or reception chain of said front-end module according to at least two modes including a first mode (M _1)/second mode (M_2) in which the processing chain presents a first/second impedance to the antenna, said first and second impedances being distinct from each other. Furthermore, said control device is intended to be integrated in said communication device and comprises a control module (MOD_CO) configured to control said switching means so that the processing chain alternates between said first and second modes and thus the communication device backscatters an ambient signal.
