1. A method for emulating a wireless channel for evaluation of a wireless signal, the method comprising:
transmitting a first trigger signal to obtain a first set of measurements of a wireless signal received at a rotating virtual circular antenna (VCA), the first trigger signal corresponding to a first position of the VCA;
transmitting a second trigger signal to obtain a second set of measurements of the wireless signal received at the VCA, the second trigger signal corresponding to a second position of the VCA different than the first position;
configuring, based on the first set of measurements, one or more output port parameters of a first channel emulator and, based on the second set of measurements, one or more output port parameters of a second channel emulator; and
transmitting an evaluation wireless signal to the first channel emulator and the second channel emulator, the output of the first channel emulator and the second channel emulator comprising an emulated multi-input, multi-output (MIMO) wireless channel.
