Abstract:
Systems and methods disclosed herein provide for preventing the mis-equalization of signals transmitted over short transmission channels. Embodiments of the systems and methods provide for a receiver including a digital receiver equalization circuit that selectively provides a correction signal to a DFE tap weight based on the value of the current DFE tap weight as well as the logical values of the in-phase and error data samples associated with received signal.
