RCE Pk (802.16 OFDMA)
RCE Relative Constellation Error is the RMS level of the Error Vector Magnitude, averaged over all subcarriers and all detected OFDM symbols. Pk is the peak level of the Error Vector Magnitude, over all subcarriers and all detected OFDMA symbols. The output provides both the percentage RCE (%) and the number of the symbol that the peak occurred. The peak symbol is the symbol number where the maximum RCE was found.
RCE pk at sym is the OFDMA symbol number where the Peak Error Vector Magnitude was detected.
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.
