Abstract: In this paper, we address the problem of unknown phase offset estimation between receivers in a multi-channel receiver system. Unknown relative phase offset between the receivers is a concern in such systems as it negatively impacts the performance of the system. In this work, we propose a least squares ellipse fit algorithm to estimate the phase offset between the receivers. We verify the performance of the algorithm against various SNR values through Monte Carlo simulations. We also compare the variance of the phase offset estimation error with CRLB. © 2013 IEEE.
