WebMultiple emitter location and signal parameter estimation. Abstract: Processing the signals received on an array of sensors for the location of the emitter is of great enough interest … Webwork on multi-speaker time delay estimation. Time delay estimation. Time delay estimation is a classic signal processing problem. In early work, Carter et al. [9] estimated time delays using generalized cross-correlation with phase transform (GCC-PHAT), which corresponds to a maximum likelihood estimate under low noise [51,7,87]. Other work uses
Webhave on-line potential [75]. Other authors use the technique to estimate time delays in MIMO environments or between multiple sensors and multiple targets [76-81]. Other authors also use power spectral density techniques to calculate the time delay [82-84]. The time delay may also be determined from a higher order spectral approach [85], The joint estimation of time delay, Doppler velocity and Doppler rate of unknown wideband signals was investigated in this paper. Taking the migrations of time delay and Doppler shift into account, a novel wideband signal model was adopted and the ML estimator was derived. See more To clearly illustrate the impact of the migrations of time delay and Doppler shift on the joint estimation of these parameters, numerical experiments using signals … See more The estimation accuracy of the proposed algorithms for narrowband cases is evaluated through numerical simulations in this section, which is assessed in … See more Performance of the approaches mentioned above for wideband cases is evaluated in this section.
