  • This paper presents a new approch for estimating the multipath time delay of signals with unknown shape from observations received by one sensor. In th? paper, a frequency domain model for the received data is developed, and multipath timo delay estimation using this model is found to be similar to DOA estimation using an array. Thus, an algorithm for estimating time delays is derived based on the ESPRIT algorithm for DOA estimation. Ambiguities arising from the model have also been analyzed, and solutions to them are provided. Simulation results verify the efficiency of this method.
