A Novel Channel Emulation Method in Multi-Probe Anechoic Chamber Setups

This paper proposes a novel channel emulation method in multi-probe anechoic chamber setups to reproduce the desired channel model within the test area. The core of the channel emulation method is how to map the desired channel model onto the limited number of probes. For the proposed method, each probe transmits the signal with parts of channel characteristics instead of rayleigh fading signal embedding all channel characteristics in the prefaded signals synthesis (PFS) method. The signal transmitted from the probe depends on the channel model and the angular location of the probe. Simulation results indicate that the field distribution and temporal correlation derived with the proposed method provide better performance. Furthermore, the accuracy of the emulated spatial correlation is the same as that with PFS if identical power weights are utilized.
