PROBLEM TO BE SOLVED: To provide an encoding system which suppresses a calculation amount and a memory capacity in a decoder. SOLUTION: The encoding system has: an encoder which has an error correction coder for generating a systematic code and transmits a parity bit to the decoder; and the decoder guaranteed to correctly receive the parity bit. The encoder is provided with an information bit storage part for storing an information bit generated in the error correction coder in addition to a parity bit storage part, and a transmission bit control part controls the transmission of one or both of the stored information bit and parity bit. The decoder is provided with: a storage part for respectively storing the received information bit or parity bit; an information bit prediction part for predicting the information bit; an input information bit generation part for generating an input information bit by combining the output of the information bit prediction part and the output of the information bit storage part; and an error correction decoding part for decoding the systematic code.
