A system for providing multi-channel multi-mode QAM equalization and carrier recovery is provided. According to one exemplary embodiment, the system includes an equalization circuit and a carrier recovery circuit operating in a concurrent manner to provide equalization and carrier recovery. The equalization circuit and the carrier recovery circuit each have two operating modes, namely, an acquisition mode and a tracking mode. The carrier recovery circuit evaluates a phase detection error calculated based on signals obtained from the equalization circuit. Based on the evaluation of the phase detection error, the equalization circuit and the carrier recovery circuit are respectively directed to switch operating mode, if appropriate.
