Claim:
1. A method comprising: generating an indicator of interference introduced by a transmitter into a spectrum of an output transmit signal prior to transmission over a transmission medium, the indicator being generated based on the output transmit signal prior to transmission; and adjusting a power level of the output transmit signal prior to transmission based on the indicator and a predetermined interference indicator level, wherein generating the indicator comprises: generating an out-of-band energy estimate of energy outside a target frequency band of the output transmit signal prior to transmission; generating an in-band energy estimate of energy inside the target frequency band in the output transmit signal prior to transmission; and generating the indicator based on the out-of-band energy estimate and the in-band energy estimate, the indicator indicating a carrier-to-interference (C/I) ratio of the output transmit signal prior to transmission.
