Unimodular Perfect Sequences of Length $p^s$
E.M. Gabidulin, V.V. Shorin · IEEE Transactions on Information Theory · 2005
A new class of unimodular perfect sequences of length p/sup s/, where p is a prime, is proposed. An explicit secondary construction is provided. This construction includes most of the previously known unimodular perfect sequences of length p/sup s/ as special cases. Also the proposed construction is extended to sequences with autocorrelation over /spl Zopf//sup s//sub p//sup k/, V/sub m2//spl times//spl Zopf//sub p//sup m1/, V/sub k/.
