This paper proposes a class of convolutional codes based on complementary structure to cancel the First-Adjacent Channel(FAC) interference in FM In-band On-channel Digital Audio Broadcasting(FM IBOC DAB) system. Those complementary convolutional codes, which are transmitted by frequency diversity scheme, can effectively deal with the problem in situations where the transmitted data may be lost or severely damaged. The simulation results and analysis show that complementary codes combining scheme yields a better result of 1-2 dB asymptotic code gain than identical codes combining scheme.
