Abstract: |
In this paper, a class of generalized cyclotomic binary sequences of period pq is proposed, where p and q are two distinct odd primes. By using Whiteman's generalized cyclotomy of order 4 and classic cyclotomy of order 2, the sequences are almost balanced and the exact value of their linear complexity is calculated, which shows that the proposed sequences are quite good in terms of the linear complexity. |
