Adaptive clock and equalization control systems and methods for data receivers in communications systems

Abstract

Systems and methods for adaptive clock and equalization control are provided for data receivers, which are based on a 'closed loop' sampling clock framework that employs controllable and dynamically adapted time offsets on both local data and amplitude clocks. The controllable clock offsets are dynamically adapted using signal processing methods adapted to achieve optimum sampling of data and amplitude sampling clock signals to accurately detect data bits and optimize system equalization settings, including, decision-feedback equalizer and/or an optional linear equalizer preceding a decision-feedback equalizer.
