Abstract

In this paper, we conceive novel symbol-based Color- Shift Keying (CSK)-aided concatenated coding schemes, which provide attractive performance gains over the comparable bitbased systems. Quantitatively, our 4CSK-aided and 16CSK-aided symbol-based concatenated systems require 0.8 dB and 0.45 dB lower SNR than the equivalent bit-based schemes. In terms of decoding complexity, the 4CSK-aided and 16CSK-aided systems reduce the decoding complexity by 67% and 33%, respectively. We have also analyzed the convergence behavior of our system with the aid of non-binary EXtrinsic Information Transfer (EXIT) charts adapted for symbol-based iterative CSK-assisted systems.
