Kristin Baynton,Belinda Jackson. Golay (.) introduced the . as a measure of the goodness of the sequence and conjectured an upper bound for this. His conjecture is still open. In this paper we investigate several classes of sequences coming from cyclic difference sets and determine their asymptotic merit factor.

Michele Rostan,Massimiliano Vairae zero. Such an array is equivalent to a group developed weighing matrix. These can therefore be considered as elements in the group ring ℤ. for a suitable abelian group .. Using this approach, we provide a comprehensive survey of these objects, restricting our attention mostly to the one-and two-dimensional (so called cyclic and bicyclic) cases.

Performance Indicators and Benchmarking,Hadamard and Chen families. We survey recent work which uses recursive techniques to unify these difference set families, placing particular emphasis on examples. This unified approach has also proved useful for studying semi-regular relative difference sets and for constructing new symmetric designs.
