Improving the Performance of Concatenated Convolutional Codes in the Error Floor Region

Abstract

The idea of the Bit-Interleaved Coded Modulation with Iterative Decoding (BICM-ID) is applied to classic schemes of both parallel and serial concatenation of convolutional codes (PCCC and SCCC) with Binary Phase Shift Keying (BPSK) modulation. Simulation results show that slightly modified PCCC and SCCC schemes provide significant improved performance of the encoder in the error floor region in terms of much lower bit error rate (BER).
