Abstract: PURPOSE: An error correcting method in a communication system and a correcting apparatus for the same are provided to reduce the number of retransmission caused by a frame error, thereby improving a network transmission rate. CONSTITUTION: A modulator checks a frame of a receiving signal and detects the position of data having high probability of generating an error. An error code substituting unit finds the position of data having high probability of generating an error by referring to a demodulator and searches for a different value to substitute regarding the data in the found position. A frame error checking unit checks again whether an error occurs or not in the transferred frame and delivers the transferred frame to an upper layer block or the error code substituting unit according to the checking results.
