Description

technical field

[0001] The invention relates to the testing of CDMA mobile communication terminals in the field of mobile communication, in particular to a multipath fading automatic testing system and a testing method for mobile terminals in a CDMA communication network. Background technique

[0002] The mobile communication channel has its own characteristics in the transmission process, such as reflection, diffraction, and scattering phenomena. The signals received by the antenna of the mobile terminal include direct waves, reflected waves and scattered waves, and as the position of the mobile terminal moves, the amplitude, phase and time delay of the waves change anytime and anywhere, so the signal level received by the mobile terminal is different. stable.

[0003] Multipath fading in mobile communication means that after the wireless signal is transmitted by the transmitting antenna before reaching the receiver, it will be reflected many times by different obstacles t...
