Trinomial properties of three families of nonlinear spreading sequences (GMW sequences, No sequences and Kasami sequences) are discussed in this paper. Using the trace representation, we prove that these sequences have regular trinomial pairs.

• 讨论了三类非线性扩频序列(GMW序列、No序列和Kasami序列)的三项式特性,利用这三类序列的迹表示,证明了GMW序列、No序列和Kasami序列均具有正则三项式对。
