Normal sequences of lengthsn=18, 19 are constructed. It is proved through an exhaustive search that normal sequences do not exist forn=17, 21, 22, 23. Marc Gysin has shown that normal sequences do not exist forn=24. So the first unsettled case isn=27.Base sequences of lengths 2n−1, 2n−1,n,n are constructed for all decompositions of 6n−2 into four squares forn=2, 4, 6, ..., 20 and some base sequences forn=22, 24 are also given. So T-sequences (T-matrices) of length 71 are constructed here for… Expand
On Sequences with Zero Autocorrelation and Orthogonal Designs
TLDR
The proposed methods for multiplying the length and type of sequences with elements on a set of commuting variables which have zero non-periodic autocorrelation function lead to the construction of many new orthogonal designs. Expand
Multiplication of sequences with zero autocorrelation
TLDR
Near normal sequences of new lengths n = 4m + 1 = 49,53,57 are constructed and a reformulation of Yang's powerful theorems on T-sequences is given. Expand
A construction of binary Golay sequence pairs from odd‐length Barker sequences
Binary Golay sequence pairs exist for lengths 2, 10 and 26 and, by Turyn’s product construction, for all lengths of the form 2 a 10 b 26 c where a,b,c are non-negative integers. Computer search hasExpand

New classes of orthogonal designs and weighing matrices derived from near normal sequences
TLDR
It is shown that near normal sequences of length n = 4m + 1 can be used to construct four directed sequences of lengths 2m+1, 2m-1,2m, 2 m and type (n, n) with zero NPAF, which leads to the construction of many large orthogonal designs. Expand
Classification of normal sequences
Base sequences BS(m,n) are quadruples (A;B;C;D) of {+1,-1}-sequences, with A and B of length m and C and D of length n, such that the sum of their nonperiodic autocorrelation functions is aExpand
New results with near- Yang sequences
We construct new TW -sequences, weighing matrices and orthogonal designs using near-Yang sequences. In particular we construct new OD(60(2m + 1) + 4t; 13(2m+ 1), 13(2m+ 1), 13(2m+ 1), 13(2m+ 1) andExpand

A variety of new constructions which concatenate shorter groups of sequences to obtain longer sequences to give many new restrictions on TCP's of lengths £ and deficiencies 8 = 2x, where x == £ mod 4. Expand
Amicable matrices and orthogonal designs
This thesis is mainly concerned with the orthogonal designs of Baumert-Hall array type, OD(4n;n,n,n,n) where n = 2k, k is odd integer. For every odd prime power pr, we construct an infinite class ofExpand

Addendum to further results on base sequences, disjoint complementary sequences, OD(4t; t, t, t, t) and the excess of Hadamard matrices
It is known that if there are base sequences of lengths m + p, m + p, m, m and y is a Yang number then there are T-sequences of length (2m + p)y. Let G = {g : g = 2a10b26c, a, b, c non negativeExpand
