Subspace-based estimation of time delays and Doppler shifts

• This paper considers the problem of estimating the time delays and Doppler shifts of a known waveform received via several distinct paths by an array of antennas. The general maximum likelihood estimator is presented, and is shown to require a Sd-dimensio
