description The invention provides a multi-path simulation system and method, which utilize the anechoic chamber to prevent external electromagnetic interference and prevent other uncontrollable signal transmission path generated in test and simulate the main indirect path of signal by the reflective face of the anechoic chamber. Further utilize attenuator to attenuate signal to simulate the attenuation of signal during transmission process in space. The movable table and rotary table in the anechoic chamber controlled by control unit carry dipole antenna and wireless communication device to be tested respectively. The former can change antenna position to simulate the phase difference between direct path and main indirect path of system. The latter can change the orientation of communication device to measure the air waves send/receive state of the wireless communication device to be tested.
