Pilot RCE (802.16 OFDMA)
Pilot RCE Relative Constellation Error is the RMS level of the Error Vector Magnitude, averaged over all subcarriers and all detected OFDM symbols. is the RMS value of the Error Vector Magnitudes (in dB) of the pilot subcarriers for all measured symbols.
The IEEE Institute of Electrical and Electronics Engineers. A US-based membership organisation that includes engineers, scientists, and students in electronics and related fields. The IEEE developed the 802 series wired and wireless LAN standards. Visit the IEEE at http://www.ieee.org 802.16 OFDMA standard uses the term "RCE" (Relative Constellation Error) instead of "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." (Error Vector Magnitude). The names are different, but the computed values are exactly the same.
