T. Moriuchi et K. Imamura, BALANCED NONBINARY SEQUENCES OBTAINED FROM MODIFIED NONBINARY KASAMI SEQUENCES, IEICE transactions on fundamentals of electronics, communications and computer science, E76A(9), 1993, pp. 1515-1519
Recently, the small set of nonbinary Kasami sequences was presented an
d their correlation properties were clarified by Liu and Komo. The fam
ily of nonbinary Kasami sequences has the same optimal periodic maximu
m nontrivial correlation as the family of Kumar-Moreno sequences, but
smaller family size. In this paper, first it is shown that each of the
nonbinary Kasami sequences is unbalanced. Secondly, a new family of n
onbinary sequences obtained from modified Kasami sequences is proposed
, and it is shown that the new family has the same maximum nontrivial
correlation as the family of non-binary Kasami sequences and consists
of the balanced nonbinary sequences.
