UnmodRCE (802.16 OFDMA)

UnmodRCE (dB) "unmodulated 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 level of the Error Vector Magnitude of all the unallocated subcarriers of the signal. UnmodRCE quantifies the amount of noise present in the unallocated subcarriers of the signal. This is important for predicting the impact of a single mobile terminal’s imperfections on multiple access of the OFDMA channel.
