Estimation of Time Delay using Super Resolution Algorithms

Abstract

In signal processing, sonar, radar, seismic waves, and radio waves, time delay estimation (TDE) has long been studied. This work employs the Matrix Pencil Method to recover super-resolution Time Delay Estimation (TDE) of signals in multi-path situations (MPM). To test the novel strategy, errors were measured and compared to the classical Multiple Signal Classification (MUSIC) and cross-correlation approaches. TDE performance in a multi-channel context is examined using numerical simulations that demonstrate varied values of mean square errors versus signal to noise ratio with separation.. The suggested super-resolution MPM methodology improves earlier approaches by precisely identifying and measuring all components to their resolution limits and addressing closely spaced frequencies. © 2022 IEEE.
