Error control encoding system

摘要

An error control encoding method and a mobile data communication system using the method in a moving body communication system such as mobile telephone for effecting data communication through a fading channel dominated by a burst error, upon receiving data transmitted from the transmitting side on the receiving side, detects any error involved in said received data as a frame error rate involved in block data or a bit error rate in the block data and thereby changes the frame length in response to the detected error rates. The mobile data communication system employs the error control encoding method wherein a frame length employed in the transmitting part is changed in response to the extent of any involved error in the received data detected by the remote receiving part.
