1. A turbo decoder comprising:
a first soft input soft output (SISO) decoder configured to receive systematic information, first parity information, and a first pre-log likelihood ratio (pre-LLR), and to output a first parity log likelihood ratio (LLR) obtained by calculating an LLR for the first parity information;
an interleaver configured to interleave the systematic information;
a second SISO decoder configured to receive an output of the interleaver, second parity information, and a second pre-LLR, and to output a second parity LLR obtained by calculating an LLR for the second parity information; and
an interference canceller configured to receive the first parity LLR from the first SISO decoder, receive the second parity LLR from the second SISO decoder, and calculate a first update parity LLR and a second update parity LLR,
wherein the turbo decoder uses the first and second update parity LLRs to derive decoded output data corresponding to the systematic information.
