1. A receiver comprising circuitry configured to:
receive a signal,
measure signal-to-noise ratio (SNR) of a first signal, wherein the first signal is a pilot or training signal associated with the received signal,
extrapolate the SNR of the first signal to determine an SNR of a second signal, wherein the second signal is a data signal for the received signal, and
determine a pre-forward error correction (FEC) bit error ratio (BER) for the second signal based on the determined SNR of the second signal, wherein the SNR is measured of the first signal and extrapolated to the second signal responsive to
the second signal being beyond a FEC threshold.
