Transmission space reproduction method and transmission space reproduction device

A transmission space reproduction device comprising:

• a propagation characteristics calculation circuitry configured to perform simulation while sequentially changing a parameter in a reverberation chamber used to reproduce propagation characteristics so as to calculate propagation characteristics in the reverberation chamber;
• a machine learning circuitry configured to form a learning model for a parameter calculated by the propagation characteristics calculation circuitry by machine learning using actually measured propagation characteristics and parameters;
• a parameter generation circuitry configured to generate a parameter corresponding to propagation characteristics to be reproduced using the learning model formed by the machine learning circuitry;
• and
• a reproduction execution circuitry configured to control a channel emulator based on the parameter generated by the parameter generation circuitry so as to perform processing of forming a transmission space having the propagation characteristics to be reproduced in the reverberation chamber.
