摘　　要：在跳频多址通信中,具有良好相关性能的跳频序列集至关重要。首先在有限扩域和子域之间定义了一类特殊函数,然后根据d型函数特有的性质,复合这两种函数,构造了一类新的达到Peng-Fan界的最佳跳频序列集。最后,给出小结,提出后续解决的问题。Frequency-hopping sequences with good hamming correlation properties is imporant in frequency-hopping multiple access systems. In this paper, a function from the finite extension field to the subfield is defined and according to the properties of form function, a new optimal frequency-hopping sequences reaching to the Peng-Fan boundary via combining these two functions is constructed. Finally, summary is given, putting forward problems to resolve.
