LDPC Error Floor Improvement [PDF]
Engineering and Technology Journal, 2012 The error-correcting performance of low-density parity check (LDPC) codes, when decoded using practical iterative decoding algorithms, is known to be close to Shannon limits.

Bit Error Floor Reduction for MQAM Signals in the Presence of Phase Error
IEEE Access, 2022 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.

Trapping Sets of Quantum LDPC Codes [PDF]
Quantum, 2021 Iterative decoders for finite length quantum low-density parity-check (QLDPC) codes are attractive because their hardware complexity scales only linearly with the number of physical qubits.

Constellation labeling maps for low error floors [PDF]
IEEE Transactions on Wireless Communications, 2007 A constellation labeling map is the assignment of a bit pattern to each symbol in a signal-set constellation. In a system with iterative decoding and demodulation, the error floor of the bit error rate is highly dependent on the labeling map. A simple class of labeling maps that significantly lower the error floors is presented.
