摘要：
A communication system according to the present invention comprises a transmitter for performing low-density parity-check (LDPC) coding and a receiver for performing LDPC decoding based on the “Sum-Product algorithm”, and performing a synchronous control and a user detection by using a sum of absolute values of logarithm likelihood ratio of the posterior probability of each bit that is output as a decoding result.
