Abstract
A communication system that performs encoding and decoding for communication includes a transmitting apparatus and a receiving apparatus. The transmitting apparatus includes a turbo encoding unit including a first encoding unit that encodes an input signal and generates a first parity bit by bit-based encoding and n (n=1, 2, 3, . . . ) second encoding units that encode the input signal and generate second parity bits by bit-based encoding, and a symbol mapping unit that maps an output from the turbo encoding unit to a symbol by bit-based mapping operation and modulates the output. And the receiving apparatus includes a demodulating unit that demodulates a transmission signal, and a turbo decoding unit that performs turbo decoding on the demodulated signal by bit-based decoding.
