1. A method comprising:
receiving calibration values determined from a plurality of received upstream signals at different respective frequencies;
using the calibration values to determine constants in a continuous function relating power adjustment to signal frequency;
using the continuous function to determine a power adjustment associated with an entire OFDMA channel; and
instructing at least one upstream transmitter to transmit an upstream OFDMA signal conforming to the determined power adjustment.
