Class Information
Number: 714/759
Name: Error detection/correction and fault detection/recovery > Pulse or data error handling > Digital data error correction > Forward correction by block code > Look-up table encoding or decoding
Description: Subject matter having an encoder or decoder which contains a table of all possible error patterns in a corrupted received code word and compares the computed syndrome to these patterns to determine the position of erroneous bits.
