New classes of quaternary cyclotomic sequence of length 2pm2pm with high linear complexity

In this paper, we introduce a new class of quaternary cyclotomic sequence over F4F4 with period 2pm2pm. We prove that the constructed sequences possess high linear complexity.

► A new class of quaternary cyclotomic sequences over F4F4 of length 2pm2pm is proposed.
► The new derived sequences are balanced and possess high linear complexity.
► Our construction includes several known results as special cases.
