Outline of Final Research Achievements |
The study of optical orthogonal codes is motivated by an application in optical orthogonal code-division multiple-access communication systems. To simultaneously support multimedia services, multilength or variable weight optical orthogonal codes are essential. We gave a construction method for multilength optical orthogonal codes with weight three. We have shown that some optical orthogonal codes obtained from lines of a projective space satisfy the property called λ-compatible and they yield some new infinite class of multilength optical orthogonal codes with weight three.
