摘要

This paper describes a $KM^{2}times M$, $Kin {BBQ }$, $M, KMin {BBZ }$, Zak space construction of zero correlation zone polyphase sequence sets, of sequence length $KM^{3}$ and set size $KM$ , with all-zero cross correlation. The construction includes the sets with an $(M-1)$-point and $(T_{2}M-1)$ -point zero autocorrelation zone, where $T_{2}$ is an arbitrary nontrivial factor of $M$. All sequences in these sets have sparse, highly structured, semipolyphase finite Zak transforms, with constant nonzero magnitude at $M$ points and zero magnitude at selectable $KM^{3}-M$ points, and sparse, semipolyphase $KM^{3}$-point discrete Fourier transforms, with constant nonzero magnitude at $M^{2}$ points and zero magnitude at selectable $KM^{3}-M^{2}$ points.
