Abstract
In this thesis, several new methods for constructing zero or low correlation zone (ZCZ or LCZ) sequence sets from the generalized Boolean functions are proposed. These methods are all direct constructions without the requirement of any special sequences or pre-search sequences and the procedures are with low complexity. The proposed methods can freely choose the sequence length, the length of ZCZ and LCZ, the set size and the number of phases as a tradeoff. Compared with previous methods, the length of ZCZ in our methods is pretty large and the length of the ZCZ can be close to the theoretical bound. Besides, the length of LCZ sequences in our method is $2^n$ and constructions for this length were not found before.
