a The estimated and measured SNR values are shown for the best single cell among the eight available cells of the OPV panel. b The number of bits loaded onto each subcarrier channel (left axis) and the measured SNR values (right axis). A greater number of bits is allocated to subcarriers that experience a higher available SNR. This is referred to as adaptive bit loading.
