Abstract:
1. A method for adjusting a signal, comprising: using an equalizer, applying at least one of a loss compensation for frequency-dependent distortion and an offset compensation for direct current offset (“DC-offset”) distortion to a signal before or after the distortion occurs to generate an output signal, the output signal comprising even phase and odd phase; using a sampler, selecting either the even phase or the odd phase at which to begin sampling; using a clock signal, beginning at the selected phase, sampling the output signal at the sampler to generate a plurality of data values and an error value, the error value indicating residue of the distortion based on the sampling of the output signal; using a controller, adjusting none, one, or more of the loss compensation and the offset compensation applied to the signal based on the sampled error value; and using the controller, after adjusting the at least one of the loss compensation and the offset compensation applied to the signal based on the sampled error value, selecting either the even phase or the odd phase at which to begin the next sampling.
