Abstract
An approach for ascertaining whether a signal is uniquely determined by its Fourier transform phase is proposed. It is shown that uniqueness corresponds to the nonsingularity of a matrix which can be formed from the finite-length real sequence. The criterion of uniqueness for reconstructing a one-dimensional finite-length sequence from its phase is discussed. The criterion of uniqueness for reconstructing a multidimensional finite-length sequence is presented
