Summary:
This letter proposes a class of polyphase zero correlation zone (ZCZ) sequence sets with low interset crosscorrelation property. The proposed ZCZ sequence sets are constructed from DFT matrices and rcoincidence sequences. Each ZCZ sequence set is optimal, and the absolute value of the crosscorrelation function of sequences from different sets is less than or equal to $rsqrt{N}$, where N denotes the length of each sequence. These ZCZ sequence sets are suitable for multiuser environments.
