Reconstructing the original complex signal using amplitude-only measurements is referred to as the phase retrieval *** this paper,we develop a fast-iterative phase retrieval algorithm that can be considered as an enhanced version of the well-known wirtingerflow(WF) *** original WF algorithm is based on gradient descent scheme to tackle the phase recovery problem,however,the convergence speed of this WF algorithm is very *** with the original WF algorithm,the proposed fast-iterative WF(FWF) algorithm has a faster convergence speed,with an acceptable little more computational *** proposed FWF algorithm is preferable not only due to its accelerated convergence speed but also due to its ability to converge to the global *** results show that the FWF algorithm is superior to the state-of-the-art algorithms in terms of the convergence speed.
