Abstract
Apparatuses, methods, and systems are disclosed for calculating an EVM of a transmitter. An apparatus includes a transceiver that receives, using an unbiased linear minimum mean square error ('MMSE') equalizer, a transmission signal transmitted via a propagation channel, the signal generated and transmitted using an antenna port at a transmitter, the antenna port comprising a plurality of antennas (N) and an antenna connector for each of the plurality of antennas. The apparatus includes a processor that determines an EVM for the antenna port of the transmitter based on an output of the unbiased linear MMSE equalizer.
