In this paper, we propose a new generation algorithm of multi-length time-and-frequency-hopping codes for the optical code-division multiple access network. The generation algorithm is more flexible compared to the conventional multilength code generation algorithms, and thus can provide more sophisticated multimedia service differentiation with respect(More)
We investigate a general scheme of frequency-hopping optical orthogonal codes with a specified distance between adjacent frequency symbols and propose a novel code that allows time blanks between adjacent frequency symbols in code sequences. A time blank represents the absence of frequency symbols in code sequences and makes no interference with frequency(More)
