  • Patent number: 11428723
    Abstract: A method for emulating an electromagnetic environment, EME, in an anechoic chamber comprises the steps of: receiving, by a first receiving unit, an input signal outside the anechoic chamber; generating, by a signal generating unit, an emulated signal based on the input signal; transmitting, by a transmitting unit, the emulated signal inside the anechoic chamber to emulate the EME; receiving, by a second receiving unit, the emulated signal inside the anechoic chamber; and adjusting, by the signal generating unit, the emulated signal generated by the signal generating unit based on the emulated signal received by the second receiving unit.
