Method and system for testing wireless performance of wireless terminal

A system for testing wireless performance of a wireless terminal, comprising an anechoic chamber, testing antennas, a channel emulator, an analog base station, and a DUT controller, wherein:

• the anechoic chamber is configured to place the testing antennas and a device under test (DUT);
• the testing antennas are configured to receive a-signals transmitted by a-transmitting antennas of the DUT, and sending the received signals to the channel emulator;
• the testing instrument is configured to obtain antenna pattern of a plurality of transmitting antennas of the DUT, import the antenna pattern into the channel emulator, select a same number of testing antennas in the anechoic chamber as a number of the transmitting antennas of the DUT, so that the transmitting antennas of the DUT transmit signals to the selected testing antennas to generate a propagation channel matrix between the transmitting antennas of the DUT and the selected testing antennas;
• the DUT controller is configured to control the DUT to load an inverse matrix of the propagation channel matrix on original signals to get loaded signals and transmit the loaded signals to the selected testing antennas through the transmitting antennas of the DUT;
• the channel emulator is configured to receive signals from the testing antennas, process the received signals based on the antenna pattern and a preset channel model to obtain an analog signal, and send the analog signal to the analog base station;
• and
• the analog base station is configured to receive the analog signal, and perform a throughput test to obtain an uplink wireless performance of the DUT.

A non-transitory computer-readable storage medium, having stored therein instructions that, when executed by a processor, causes the processor to perform a method for testing wireless performance of a wireless terminal, wherein the wireless terminal is configured as a device under test (DUT), the DUT has a plurality of transmitting antennas and is placed in an anechoic chamber, and the method comprises:

• obtaining antenna pattern of the plurality of the transmitting antennas of the DUT, and importing the antenna pattern into a channel emulator;
• selecting a same number of testing antennas in the anechoic chamber as a number of the transmitting antennas of the DUT, so that the transmitting antennas of the DUT transmit signals to the selected testing antennas to generate a propagation channel matrix between the transmitting antennas of the DUT and the selected testing antennas;
• wherein the propagation channel matrix is eliminated during signal transmission from the DUT to an analog base station by:
• the DUT loading an inverse matrix of the propagation channel matrix on original signals to get loaded signals, the transmitting antennas of the DUT transmitting the loaded signals to the selected testing antennas, the selected testing antennas receiving signals from the transmitting antennas of the DUT, sending the received signals to the channel emulator, and the channel emulator processing the received signals based on the antenna pattern and a preset channel model to generate an analog signal and sending the analog signal to an analog base station;
• and
• the analog base station receiving the analog signal and performing a throughput test to obtain an uplink wireless performance of the DUT.
