摘要: 以GMW序列为基础设计了GMW-几何序列, 并计算了两种情况的GMW-几何序列的相关函数.当f, g为平衡函数时, GMW-几何序列容易生成且其相关函数具有较理想的特性.因而在直扩码分多址通信系统中有实用价值.最后, 给出了4种情况的GMW序列的相关函数.

Abstract: Based on GMW sequences, a family of GMW-geometric sequences are constructed, and their correlation functions in two cases are given.When f,g are balanced functions, GMW-geometric sequences are not only generated easily but also have good correlation property. As a result, GMW-geometric sequences can be applied in direct spectrum code-division multiple access communication systems. At last correlation functions of GMW sequences in four casesare given out as corollaries.

Key words: correlation functions, GMW-geometric sequences, GMW sequences
