DOI: 10.1109/access.2022.3232078
Abstract: We propose a method to form a non-uniform decision boundary (NUDB) for $M$ -ary quadrature amplitude modulation (MQAM) signals to reduce bit error floor (BEF) in the presence of phase error. We put our focus… read more here.

DOI: 10.1109/lcomm.2018.2864982
Abstract: This letter presents a low-complexity redecoding-based error-floor lowering technique for quasi-cyclic low-density parity-check codes, where a predetermined set of variable nodes are attenuated before the redecoding. Using a two-stage off-line search, the attenuation set is… read more here.
