Abstract
This paper describes a new algorithm for parameter estimation of multichannel single-tone signals. The algorithm works in the frequency domain and uses a least square optimization to estimate the signals’ amplitudes, phases and common frequency. The performance of the algorithm is shown on both simulated and measured signals.
