1. A method performed by an evaluation device, the method comprising:
receiving an output from an antenna port, wherein the antenna port comprises a linear combination of two or more transmit antennas;
performing normalized maximum ratio combining on the output of the antenna port to produce a normalized output; and
determining a signal quality of the output of the antenna port, wherein determining the signal quality comprises determining an error vector magnitude using the normalized output.
