ABSTRACT:
Methods, apparatuses, and systems are presented for performing channel equalization involving receiving a signal from a channel associated with inter-s interference (ISI), providing the received signal to an inductor, capacitor, resistance (LCR) network comprising a plurality of inductors and a plurality of capacitors, generating in the LCR network a first plurality of intermediate signals representing voltages associated with capacitors in the LCR network and a second plurality of intermediate signals representing currents associated with inductors in the LCR network, wherein the first plurality and second plurality of intermediate signals correspond to application of linearly independent impulse responses to the received signal, applying a corresponding one of a plurality of multiplier factors to each of the first plurality and second plurality of intermediate signals, and generating from the LCR network a resulting signal corresponding to an equalized version of the received signal.
