Linear complexity of Whiteman-generalized cyclotomic sequence with order four
一类新的4阶W-广义割圆序列的线性复杂度*

Based on the Whiteman-generalized cyclotomy,this paper constructed a new class of generalized cyclotomic sequences with length pq and order 4 over Zpq by finding out a special characteristic set.It detemined the linear complexity of the sequences, and balanced the sequence. It is shows that the sequence has good linear complexity, and it can resist attacks from the application of the Berlekamp-Massey algorithm.
