The EVM (Error Vector Magnitude) measurement is mandatory for radio equipment test. Signals transmitted from multiple antennas give high EVM value due to the phase difference in near field OTA (Over The Air) test. To overcome this difficulty, near field EVM measurement using channel estimation is examined in this paper.
