Hadamard matrices, Baumert-Hall units, four-symbol sequences, pulse compression, and surface wave encodings

R.J Turyn
1974 Journal of combinatorial theory. Series A  
The constructions relate to various topics such as pulse compression and image encodings. 313  ...  A number of special Baumert-Hall sets of units, including an infinite class, are constructed here; these give the densest known classes of Hadamard matrices.  ...  have recently been considered in connection with surface wave encodings.  ...

Finding high-order Hadamard matrices by using quantum computers [article]

Andriyan Bayu Suksmono, Yuichiro Minato
2020 arXiv   pre-print
Previously, we have shown that the H-SEARCH; which is the problem of finding a Hadamard matrix (H-matrix) among all possible binary matrices of corresponding order, is a hard problem that can be solved  ...  This method is potentially capable to find some unknown H-matrices of practical and scientific interests, where a classical computer alone cannot do because of the exponential grow of the complexity.  ...  Thoughts on inverse orthogonal matrices, simultaneous sign successions, and tessellated  ...
