Abstract :
This correspondence presents a phase unwrapping (PU) algorithm based on the matrix pencil (MP) method. A brief discussion is given on the relationship between PU and instantaneous frequency estimation. The PU algorithm and its properties are presented in detail. Results show a significant improvement in PU with respect to previous algorithms.
