Summary:
An uncorrelated asymmetric ZCZ (UAZCZ) sequence set is a special version of an asymmetric ZCZ (AZCZ) sequence set, which contains multiple subsets and each subset is a typical ZCZ sequence set. One of the most important properties of UAZCZ sequnence set is that two arbitrary sequences from different sequence subsets are uncorrelated sequences, whose crosscorrelation function (CCF) is zeros at all shifts. Based on interleaved technique and an uncorrelated sequence set, a new UAZCZ sequence set is obtained via interleaving a perfect sequence. The uncorrelated property of the UAZCZ sequence sets is expected to be useful for avoiding intercell interference of QSCDMA systems.
