Rician Channel Modeling for Multiprobe Anechoic Chamber Setups

This letter discusses over-the-air (OTA) testing for multiple-input-multiple-output (MIMO)-capable terminals, with emphasis on modeling Rician channel models in the multiprobe anechoic chamber setups. A technique to model Rician channels is proposed. The line-of-sight (LOS) component, within arbitrary polarization and an arbitrary impinging direction, and non-LOS (NLOS) component, with any impinging power angular spectrum (PAS), can be created. Simulation results show that the emulated Rician channels approximate the target models accurately in terms of field envelope distribution, K-factor, Doppler spectrum, and spatial correlation at the receiver (Rx) side.
