DOI: 10.1109/cc.2018.8398515
Abstract: In the Davey-MacKay (DM) construction, the inner decoder treats unknown transmitted bits as random independent substitution errors. It limits the synchronization capability of the inner decoder, and thus weakens the error-correcting capability of the DM… read more here.

DOI: 10.1109/jlt.2017.2753819
Abstract: In super-Nyquist wavelength division multiplexed (WDM) systems with frequency spacing smaller than the signal baudrate, the maximum-likelihood (ML) decoder in the receiver is usually introduced to compensate for intersymbol interference due to tight spectral filtering,… read more here.

DOI: 10.1109/lcomm.2018.2878719
Abstract: In this letter, we design a bit-interleaved polar-coded modulation system with iterative decoding subject to constraints on complexity, error floor, and waterfall region performance. We show that the hill-like trajectory of polar code extrinsic information… read more here.

DOI: 10.1109/tmag.2019.2891711
Abstract: This paper focuses on the shingled magnetic recording (SMR) as the recording system for further high-density hard disk drives. Previously, we applied a log-likelihood ratio (LLR) modulator to the low-density parity check coding and iterative… read more here.
