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