ABSTRACT:
A method and apparatus to compensate for spectral attenuation are described wherein the spectral attenuation for a communications channel is determined, a first filter is created for the attenuation and the first filter compensates for the attenuation. The spectral attenuation for the communications channel is determined by a received L sequence signal that is used to model the spectral attenuation as a second filter. Other embodiments are described and claimed.
