An apparatus for receiving data block-interleaved and multi level/phase modulated data and restoring the block-interleaved multi level/phase modulated data into original data, comprises a demodulation and error correction portion for demodulating and error-correcting data to be received and outputting the modulated and error-corrected data; a synchronization portion for generating a fixed sync position signal, based on the comparison between the data output from the demodulation and error correction portion and stored block sync data; and a block deinterleaver for block-deinterleaving the data which is output from the demodulation and error correction portion according to the fixed sync position signal. The apparatus makes certain that a sync signal for block deinterleaving is identical to a sync signal at the transmission end and performs block deinterleaving even though no error correction is made. Furthermore, the present invention is capable of reliably detecting a sync signal, even when the sync signal is momentarily deviated because error correction is not completely made.
