PilotEVM (802.11a/g/j/p OFDM)

PilotEVM is the RMS value of the Error Vector Magnitudes (in dB) of the four pilot subcarriers for all symbols over the entire burst. For 802.11a this includes the SIGNAL symbol.

The IEEE developed the 802 series wired and wireless LAN standards.

OFDM is an alternative tranmission scheme to DSSS and FHSS. and HIPERLAN/2 specifications show EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. in units of decibels (dB).
