Abstract
Methods, apparatuses, and systems are presented for performing channel equalization comprising receiving a signal from a channel associated with inter-symbol interference, processing the received signal to effectively apply a plurality of linearly independent impulse responses to the received signal to produce a plurality of intermediate signals, scaling each of the intermediate signals by each of a plurality of multiplier factors to produce a plurality of scaled signals, and combining the scaled signals to produce a resulting signal corresponding to an equalized version of the received signal in order to reduce effects of inter-symbol interference. Processing of the received signal may comprise providing the received signal to an LCR network comprising a plurality of inductors and a plurality of capacitors and generating, as the intermediate signals, a plurality of inductor signals representing currents through the plurality of inductors and a plurality of capacitor signals representing voltages across the plurality of capacitors.
