| 1. A method comprising:
receiving a signal transmitted over subcarriers;
estimating power gains of said subcarriers from said received signal;
determining a channel deviation of said subcarriers;
providing a modulated signal for transmission over said subcarriers;
calculating subcarrier weights for said modulated signal, wherein said subcarrier weights are inversely proportional to said
estimated power gains if said channel deviation is equal to or less than a predetermined threshold, and wherein said subcarrier
weights are substantially all units if said channel deviation is greater than said predetermined threshold, and wherein said
subcarrier weights are calculated so that the total transmission power remains substantially constant; and
weighting said modulated signal with said subcarrier weights.
