A new class of generalized cyclotomic sequence with period 2pq is proposed in this paper, where p and q are distinct primes. A formula for computing the linear complexity of the proposed sequence is also given. With the knowledge of the support set of the generalized cyclotomic sequence, its linear complexity can be easily determined using the formula.
