Selective Serial Concatenation of Turbo Codes Academic Article uri icon


  • A serial concatenation scheme consisting of a Bose-Chaudhuri-Hocquenghem (BCH) outer code and a Turbo inner code is proposed. We first establish that only a small number of bit positions at the Turbo decoder output are likely to be in error at high signal-to-noise ratios. A double-error correcting BCH outer code is used to protect these particular error prone bits. Simulation results for an additive white Gaussian noise (AWGN) channel show that the bit-error rate (BER) floor of the Turbo code can be lowered by using this serial concatenation scheme. The proposed technique offers higher throughput efficiency and lower complexity than other serial concatenation schemes.
