Abstract
To expedite training and achieve fast linkup times, one illustrative receiver includes: a continuous time linear equalizer configured to provide a controllable amount of high frequency boost to an analog receive signal; an analog to digital converter configured to convert the analog receive signal into a digitized receive signal; a channel estimation module configured to obtain a spectral density measurement of the digitized receive signal at each of two different frequencies, the spectral density measurements having a difference indicating a slope of a channel response; and a microcontroller configured to set at least one operating parameter of the continuous time linear equalizer based on said difference. An illustrative method includes: estimating a slope of frequency dependence of a channel response; using the slope to retrieve a set of equalization parameters from a look-up table; and employing the set of equalization parameters to exit a receiver training mode.
