Han-Doo Kim, Sung-Jin Cho · Journal of applied mathematics & informatics · 2012
Let and be two maximal length sequences of period . The cross-correlation is defined by for . In this paper, we propose a new proof for finding the values and the number of occurrences of each value of when , where , is a positive integer.
