Constructing "broad sense complementary" sequences of length 4N
Ernest E. Hollis · IEEE Transactions on Aerospace and Electronic Systems · 1967
It is shown that it is possible to construct sets of binary sequences each of length equal to 4N(where N is any natural number), which have the property that the sum of their 2Ntruncated autocorrelation functions is zero except for zero shift. The number of such sequences in any set is equal to 2N. The autor uses the term "broad sense complementary" sequences to describe the sets of codes with the above properties.
