Abstract :
A new construction was proposed to design almost optimal sequence set with zero correlation zone(ZCZ). Based on the interleaved technique and recursive algorithm, a new ZCZ sequence set can be generated from an arbitrary perfect sequence, the length of which is longer than 4. And the ZCZ width and length of the new sequence can also be extended by recursive operation. The new sequence set can approach the mathematical bound, and can successfully provide CDMA communication without co-channel interference.
