Method and circuit for erasure correction

摘要

A demodulator 101 demodulates modulated data into demodulated data, detects a demodulation error, and sets an erasure flag. An error corrector 104 performs erasure correction for the demodulated data retained in a demodulated data memory 102 by using the erasure flag retained in an erasure flag memory 103. An erasure flag eraser 105 instructs the erasure flag memory 103 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.
