DECODING METHOD AND APPARATUS USING COOPERATION BETWEEN HIGHER LAYER AND LOWER LAYER AND DATA TRANSMITTING/RECIEVING SYSTEM

摘要

PURPOSE: A decoding method using a linkage between upper and lower layers and a data transceiver system using the same are provided to significantly decrease the total number of received data bits by transmitting and receiving data at a small error rate in a given channel environment. CONSTITUTION: A lower layer decoder(722) decodes data using a lower layer code. The lower layer decoder outputs each bit of the decoded data with reliability which is equal to or greater than a set reliability threshold value. An upper layer decoder(724) decodes the bit outputted from the lower layer decoder using an upper layer code. The upper layer decoder restores the source information. The lower layer decoder is comprised of a physical layer decoder. The higher layer decoder is composed of a rateless code decoder.
