Abstract :
In this letter, zero-correlation zone (ZCZ) aperiodic complementary sequence (ZACS) sets with low column sequence peak-to-mean envelope power ratio (PMEPR) are introduced. Based on Golay sequences with large zero autocorrelation zone and orthogonal matrix, a class of ZACS sets are constructed. When each sequence is arranged to be a matrix, the PMEPR of column sequence is at most 2.
