New Eight-phase Preferred Pairs (EPPs) that have Zero-Correlation Duration (ZCD) of (0.5N+1) chips are constructed for the periods of $N=4{\times}2n$ (n=1,2,3...). By using the chip-shift operation of the EPP, new eight-phase ZCD sequences are constructed in this paper. We certified its ZCD property by various correlation simulations. This new eight-phase spreading sequence can be used for Interference cancelled wireless personal area network(WPAN) based on approximately synchronized code-division-multiple-access(AS-CDMA) system.
