ABSTRACT:
A low-complexity digital linear equalizer whose operation and adaptation makes stabilized digital timing recovery practical. The technique is fundamental for the operation of communications receivers employing digital timing recovery, e.g., in a modem. A technique for automatically adjusting the parameters of a digital linear equalizer to compensate for low-pass impairments while maintaining a relatively constant timing characteristic is described.
