One error-correcting block is composed of error-correcting code words (LDC) of 304 pieces (columns).

An error recovery system for computers is shown in which an error table (31) and an action table (32) are used to control the parameters of the error recovery system.

A second EDC is applied to the ECC (114).

correction of error from previous exercise (FY 2008

S-parameter cable correction

These initial raw bits are decoded and error-checked (or error-corrected).

go-back n RQ system

The error correction can be stepwise.

forward error-correction coding

And, the error correction unit performs error correction decoding on the decoded mobile service data, thereby correcting an error occurred in the mobile service data.

The method also includes calculating a second error correction code corresponding to a second error profile and generating (112) a second FEC packet to produce the second error correction code.

An error-code-adding error correcting circuit (60) error-corrects the EFM demodulated signal and adds error codes.

A data error control method for error correction coded data.

Error correction decoders (154-1 to 154-4) perform error correction decoding of the candidate signal whose phase and amplitude are compensated.

The invention also performs a soft decision and error correction decoding process on the enhanced data, thereby may enhance the performance of the error correction decode.
