Abstract
An early termination method with a re-encoding scheme for decoding of error correction codes is disclosed. The method includes the steps of: A. receiving soft values; B. processing hard decision on the soft value to determine a codeword; C. separating the codeword into a data part and a first parity part; D. re-encoding the data part to get a second parity part; E. checking if the first parity part and the second parity part are equivalent; and F. if a result of step E is yes, stopping decoding the codeword; if the result of step E is no, processing a decoding algorithm on the codeword. By this method, the received codeword still can be correctly decoded if there are many errors in the parity region and its decoding performance can be improved.
