Abstract
An error recovery apparatus and method of a digital broadcasting receiver includes an analog-to-digital converting (ADC) unit, a splitter, a sampling distortion compensation unit, a phase error compensation unit, and an equalizer. The ADC unit converts a broadcasting signal of an analog format into a digital format through sampling. The splitter shifts the broadcasting signal of the digital format to a baseband, and splits the broadcasting signal to an in-phase channel signal and a quadrature channel signal. The sampling distortion compensation unit compensates an error generated in the broadcasting signal due to the sampling of the ADC unit. The phase error compensation unit compensates a phase error caused by interference of the broadcasting signal when the broadcasting signal is transmitted through a multi-path channel. The equalizer removes the broadcasting signal which is not transmitted through a main path of the multi-path channel.
