  • Augmented decoders for LDPC codes 
    Rigby, Alex R.; Olivier, J.C.; Myburgh, Hermanus Carel; Xiao, Chengshan; Salmon, Brian P. (SpringerOpen, 2018-08-02)
    The performance of a belief propagation decoder for low-density parity-check codes is limited by the presence of trapping sets in the code’s graph. This leads to an error floor at higher signal-to-noise ratios. We propose ...
  • Improved BDFE using a priori information for turbo equalization 
    Wu, Jingxian; Leong, Sang-Yick; Lee, Kah-Ping; Xiao, Chengshan; Olivier, Jan Corne (Institute of Electrical and Electronics Engineers, 2008-01)
    Turbo equalization improves communication system performance by iteratively exchanging information between soft-input soft-output (SISO) equalizer and SISO channel decoder. The trellis-based maximum a posteriori robability ...
