Abstract: A method for managing a signal transmission emitted by a wireless transponder to a reader is provided in which the signal transmission uses an active load modulation and includes transmitted bursts separated by pause periods. Each transmitted burst includes transmitted pulses. The method includes performing an active damping operation at the end of the transmitted bursts in the beginning of the pause periods, and the active damping operation includes transmitting a number of additional pulses having a phase opposite to the phase of the transmitted pulses. The transmitted pulses power, the additional pulses power, and the number of additional pulses are controlled based on a distance between the reader and the wireless transponder and on reference values of the transmitted pulses power, the additional pulses power, and the number respectively associated with reference distances.
