Phase retrieval: Applications, Methods & Semidefinite relaxation-based algorithm for short time Fourier transform

Phase retrieval is the process of algorithmically finding solutions to the phase problem. Given a complex spectrum F ( k ) {\displaystyle F(k)} , of amplitude | F ( k ) | {\displaystyle |F(k)|} , and phase ψ ( k ) {\displaystyle \psi (k)} :
