Abstract
A demodulator demodulates modulated data into demodulated data, detects a demodulation error, and sets an erasure flag. An error corrector performs erasure correction for the demodulated data retained in a demodulated data memory by using the erasure flag retained in an erasure flag memory . An erasure flag eraser instructs the erasure flag memory to erase an erasure flag which is set to the corrected demodulated data. In this way, the erasure correction which has a higher correction capability and is effective particularly for burst errors is realized.
