ABSTRACT:
The present invention provides a system and method for multi-path simulation that employs a shielded anechoic chamber to avoid external electromagnetic interference and other uncontrollable transmission paths generated in testing, and divides and adjusts a signal into multiple simulation signals to simulate the attenuations and delays generated in multi-path transmission of the signals. The shielded anechoic chamber includes a turntable, controlled by a control unit, for carrying a wireless communication device to be tested and for changing the reception azimuth of the device, thereby measuring the electric wave transceiving of the device.
