Channel Modelling for Multiprobe Over-the-Air MIMO Testing

摘要: This paper discusses over-the-air (OTA) test setup for multiple-input-multiple-output (MIMO) capable terminals with emphasis on channel modelling. The is composed of a fading emulator, an anechoic chamber, and multiple probes. Creation of a propagation environment inside chamber requires unconventional radio modelling, namely, specific mapping the original models onto probe antennas. We introduce two novel methods to generate emulator coefficients; prefaded signals synthesis plane wave synthesis. To verify both we present set simulation results. also show that geometric description prerequisite model.
