Abstract
The present invention is directed to methods and systems for determining maximum power backoff for modems operating according to G.SHDSL and other standards using frequency domain geometric signal to noise ratio (SNR). In one example, a G.SHDSL standard may specify a minimum power back off (PBO) that may be required for modem implementation. Although the standard specifies the minimum back off, it is desirable to be able to increase the PBO beyond this level. The reasons for this may include reduced power consumption and reduced crosstalk generated by a modem. The present invention discloses a method and system for determining an absolute maximum power PBO that may be tolerated and still meet bit error rate (BER) and/or other requirements. The present invention implements a geometric mean to compute SNR in a frequency domain over a pass-band of a transmit spectrum.
