Abstract
Wireless cable method is a strong candidate to replace conductive cable method for performance testing of multiple-input multiple-output (MIMO) devices. Desired testing signals can be guided over-the-air to the corresponding antenna ports of the mobile terminals, via implementing a compensation filter in the channel emulator (CE). A novel wireless cable method, without the knowledge of transfer matrix between the CE output ports and device antenna ports, was recently proposed in the literature. In this method, the compensation filter was determined based on the average power recorded by each device antenna ports. To speed up the calibration procedure, a one-dimensional monotonic search method was proposed. However, the calibration accuracy was lower comparing with the brute-force method. In this paper, a high-efficiency particle swarm optimization (PSO) algorithm is proposed to determine the compensation filter. Numerical simulation results are provided to validate the effectiveness of PSO algorithm for compensation filter determination in the wireless cable testing.
