摘要
讨论了扩频序列设计中的二次型方法。利用有限域上二次型理论求出了Kasami序列及其变种和Kumar-Moreno序列及其变种的相关函数值,同时也决定了Kasami序列和Kumar-Moreno序列的Hamming相关函数值。
The quadratic forms methods in spreading sequences designs are discussed in this paper. We calculated the correlation function values of Kasami sequences, Kumar ?Moreno sequences and their generations. In the meanwhile we also determine the Hamming correlation function values of Kasami sequences and Kumar-Moreno sequences by using the theory of quadration forms over finite fields.
