An E8-VSB reception system system is provided. A VSB receiver converts a received broadcast signal into a digital baseband signal in synchronization with a first symbol clock, converts a decision signal synchronized with a second symbol clock into a decision signal synchronized with the first symbol clock, performs channel equalizing and noise removal on the digital baseband signal using the converted decision signal, performs error correction on the noise removed signal, and outputs error-corrected data and a synchronization signal in synchronization with the first symbol clock and second symbol clock. A E8-VSB data processor receives the data and the synchronization signal in synchronization with the first symbol clock and second symbol clock from the VSB receiver, extracts enhanced data according to the synchronization signal, performs E8-VSB decoding and error correction, and outputs the decision signal synchronized with the second symbol clock to the VSB receiver.
