Pseudocodewords of quantum, quasi-cyclic, and spatially-coupled LDPC codes: a fundamental cone perspective
Wittawat Kositwattanarerk, Gretchen L. Matthews, Emily McMillon +1
While low-density parity-check (LDPC) codes are near capacity-achieving when paired with iterative decoders, these decoders may not output a codeword due to the existence of pseudo…
Dynamic Exponent Market Maker: Personalized Portfolio Manager and One Pool to Trade Them All
Wittawat Kositwattanarerk
Decentralized exchange platforms such as Uniswap and Balancer operate on several pools where each pool contains two or more cryptocurrencies and constitutes direct trading pairs. T…
Pseudocodeword-Free Criterion for Codes with Cycle-Free Tanner Graph
Wittawat Kositwattanarerk
Iterative decoding and linear programming decoding are guaranteed to converge to the maximum-likelihood codeword when the underlying Tanner graph is cycle-free. Therefore, cycles a…
Multidimensional Fibonacci Coding
Perathorn Pooksombat, Patanee Udomkavanich, Wittawat Kositwattanarerk
Fibonacci codes are self-synchronizing variable-length codes that are proven useful for their robustness and compression capability. Asymptotically, these codes provide better comp…
Construction A of Lattices over Number Fields and Block Fading Wiretap Coding
Wittawat Kositwattanarerk, Soon Sheng Ong, Frédérique Oggier
We propose a lattice construction from totally real and CM fields, which naturally generalizes the Construction A of lattices from -ary codes obtained from the cyclotomic field…
Connections Between Construction D and Related Constructions of Lattices
Wittawat Kositwattanarerk, Frédérique Oggier
Most practical constructions of lattice codes with high coding gains are multilevel constructions where each level corresponds to an underlying code component. Construction D, Cons…
