Abstract
This paper discusses quasi-orthogonal sequences consisting of real elements, whose periodic out-of-phase autocorrelation functions take zero except for a shift corresponding to the half period. It is shown that they can be formalized by use of the Fourier transform. As a special case, binary quasi-orthogonal sequences are found until period 196 from a conjecture for their constructions.
