This paper discusses over-the-air (OTA) test setup for multiple-input-multiple-output (MIMO) capable terminals with emphasis on channel BUTTON DOWNS modelling.The setup is composed of a fading emulator, an anechoic chamber, and multiple probes.Creation of a propagation environment inside an anechoic chamber requires unconventional radio channel modelling, namely, a specific mapping of the original models onto the probe antennas.We introduce 8 Piece Sectional with Chaise two novel methods to generate fading emulator channel coefficients; the prefaded signals synthesis and the plane wave synthesis.To verify both methods we present a set of simulation results.
We also show that the geometric description is a prerequisite for the original channel model.
