A discrete mathematics lab that builds codes for communication from combinatorial structures.

AboutAbout the lab
Building communication codes from combinatorial structures
The Miyamoto Lab studies combinatorial designs, combinatorial arrays, and the combinatorial structures of finite geometries, among other topics.
In optical fiber communication, the lab found a way to construct optical orthogonal codes, which are used to extract the signal addressed to oneself from overlapping signals, using lines in a projective plane.
On the lab's website, it is introduced under the name "Miyamoto Lab / Discrete Mathematics Lab."
The content of the lab's website dates from around fiscal year 2019.
Key terms
- Optical orthogonal codes
- Codes used in optical fiber communication when one wants to extract only the signal addressed to oneself from overlapping signals
- Projective plane
- A plane with points at infinity added so that even parallel lines meet at a single point
- Combinatorial designs
- Structures in which a set of elements is divided or arranged into subsets so as to satisfy given conditions
ResearchResearch themes
The Miyamoto Lab website lists the construction of combinatorial designs, the construction of combinatorial arrays, the construction of optical orthogonal codes, and the study of combinatorial structures in finite geometries as its research. Of these, optical orthogonal codes are presented together with their uses in communication.
