ERROR CORRECTION DECODER AND ERROR CORRECTION DECODING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an error correction decoder that can obtain desired transmission quality even when each signal sequence cannot completely be separated at once. SOLUTION: A decoder 211 applies error correction decoding to an input signal for a user A. A replica generator 221 encodes an output signal from the decoder 211 to generate a replica signal for the user A. An adder 231 subtracts the replica signal for the user A generated by the replica generator 221 from the input signal. A decoder 212 applies error correction decoding to an output signal from the adder 231 for a user B. A replica generator 222 encodes an output signal from the decoder 212 to generate a replica signal for the user B. An adder 232 subtracts the replica signal for the user B generated by the replica generator 222 from an output signal from a delay device 202.
