Conjecture on the effect of coset-representative choices on intra-set MSED
Conjecture on coset-representative choices. There would be no big difference in performance between different choices of the set of coset representatives or of the mapping within t…

Universal near-capacity conjecture for QC-TE-SC-PLDPC codes in higher-order BICM-ID systems
A QC-TE-SC-PLDPC code is a quasi-cyclic spatially coupled protograph-based low-density parity-check code with terminated expansion. BICM-ID denotes bit-interleaved coded modulation…

Conjecture on asymptotic equivalence of symbol-based and bit-based decoders
Consider symbol-based and bit-based decoders for coded modulation, including the maximum-likelihood symbol-wise decoder and the suboptimal bit-wise decoder based on max-log L-value…

Conjecture on asymptotic equivalence of bit-wise and symbol-wise decoders for linear codes
Let a linear code be used over a flat fading channel, and let the B-DEC denote the bit-wise decoder and the S-DEC denote the symbol-wise decoder. Asymptotic equivalence conjecture.…
