Abstract: Overlapped frequency division multiplexing (OVFDM) systems can obtain high spectral efficiency (SE), which is proportional to the constraint length. However, high decoding complexity imposes the main challenge on OVFDM systems. This paper proposes a low-complexity… read more here.

DOI: 10.1109/access.2018.2873821
Abstract: In successive cancellation (SC) polar decoding, an incorrect estimate of any prior unfrozen bit may bring about severe error propagation in the following decoding, and thus it is desirable to find out and correct an… read more here.

DOI: 10.1109/lcomm.2018.2809718
Abstract: This letter proposes a novel two-bit weighted bit-flipping algorithm (TB-WBFA) for low-density parity-check (LDPC) codes on the binary symmetric channel. The proposed TB-WBFA produces reliability bits for the bit-decision results and syndrome values at bit… read more here.

DOI: 10.1109/tcsii.2020.2984536
Abstract: Due to its parallel propagation property, the belief propagation (BP) polar decoding can achieve high throughput and has drawn increasing attention. However, the BP decoding is not comparable with the successive cancellation list (SCL) decoding… read more here.
