Abstract

The invention provides a testing device of simulation system with multipath and a method thereof. The testing device comprises an absorption chamber for radio wave isolation which can avoid electromagnetic interference from outside and other unexpected transmission paths. The multipath simulation system simulates communication effect of MIMO passage communication environment through an attenuator. A control unit can set a testing device, a reference device and a device to be tested of MIMO and SISO system, so as to determine attenuation difference of the testing device, the reference device and the device to be tested and loading difference of upper / lower chains. The testing device of multipath simulation system and the method of the invention have the advantages of easy control, short treatment time, easy adjustment and low cost, etc.

Description

technical field [0001] The present invention relates to a test device and method for a multi-path simulation system, in particular to a shielded anechoic chamber to avoid external electromagnetic interference or other unexpected transmission paths with multiple inputs and multiple outputs. input multiple output; MIMO) system. Background technique [0002] With the rapid development of wireless communication technology, the use of technologies such as mobile phones and wireless local area networks has become more common. The same is expected for the ensuing wireless metropolitan area network applications. Compared with the real route (real route) signal transmission with a fixed channel, the wireless signal transmission has the characteristic of multiple paths. Multiple paths mean that when a wireless signal propagates in space, it encounters obstacles such as walls and generates reflections. Therefore, there are multiple paths of electric wave transmission between the tran...
