Title:
TEST METHOD, TRANSMITTING APPARATUS, TEST APPARATUS AND TEST SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/196499
Kind Code:
A1
Abstract:
Provided is a test method, comprising: after transmitting N signal sequences through a transmitting antenna array, a transmitting apparatus obtaining a phase offset of each signal sequence of the N signal sequences passing through channels from a test apparatus, and adjusting an initial test signal according to the phase offset of each signal sequence passing through channels to obtain a target test signal capable of being superposed in phase at the test apparatus; the target test signal being a plurality of signal sequences obtained by respectively adjusting phase of the initial test signal according to the phase offset of each signal sequence passing through the respective channel; and then transmitting the target test signal through the transmitting antenna array. This makes the phase-adjusted test signal form in-phase superposition at a position of a receiving antenna, so as to obtain an effective signal, and then calculate a signal index of the transmitting apparatus. Since a near-field test can be realized without reflector, the cost of near-field test can be reduced. The present application further discloses a transmitting apparatus, a test apparatus and a test system capable of achieving the above method.
