A quadriphase sequence pair whose aperiodic auto/cross-correlation functions take pure imaginary values
This paper presents a quadriphase sequence pair, whose aperiodic auto-correlation functions for non-zero shifts and cross-one for any shift take pure imaginary values. Functions for pairs of length 2(n) are formulated, which map the vector space of order n over GF(2) to Z(4). It is shown that they are bent for any n, such that their Fourier transforms take all the unit magnitude.
