A digital signal communication system is described which can operate in harsh wiring networks. The signal processor includes a transmitter circuit and a receiver circuit for transmitting and receiving data signals over noisy wiring networks, such as household AC power networks. The receiver circuit uses a digital signal detector which detects a signal arrive time and a phase of a detected signal, and normalizes an amplitude of the receive signal. The receiver circuit also uses a digital channel equalizer with an auto step selection and a coefficient-relaxing scheme for convergence in harsh wiring environments.
