Generation and performance analysis of frequency-hopping optical orthogonal codes with arbitrary time blank patterns

We propose a new generation algorithm for frequency-hopping optical orthogonal codes (FH-OOC). The new algorithm generalizes the conventional FH-OOCs by considering the time blank patterns between two adjacent symbols. We show that it can generate more available codes than the previous algorithm which does not consider the effect of time blank patterns. We also derive the upper bound of the new code set. We conduct the performance analysis by considering the interference from unwanted frequency components, and compare the bit error rate of the new codes with those of other code sets in various cases.
