METHOD AND SYSTEM FOR TESTING OVER THE AIR PERFORMANCES IN MULTI-ANTENNA SYSTEM |
摘要 |
<p>The present invention discloses a method and system for testing OTA performance in a multi-antenna system. Multiple antennas are set in an anechoic chamber; a BS simulator is controlled to transmit benchmark test signal to DUT through a channel emulator and antennas; when determining the benchmark test signal does not meet set requirement, the benchmark test signal is adjusted until set requirement is met; corresponding test cases are determined according to different channel models; according to channel models, the channel emulator performs channel simulation processing on test signal output from the BS simulator and sends the test signal to DUT through antennas; after DUT receives the test signal, each OTA performance is tested according to OTA performance test items corresponding to test cases; and DUT is judged to reach the standard when all OTA performances reach the standard. The present invention is easy to implement and has a low cost.</p> |
