Analysis of ESPRIT-Based Algorithms for Blind Frequency Offset Estimation on MC-CDMA Downlink
Yen‐Chen Chen · IEICE Transactions on Communications · 2006
In this letter, we investigate ESPRIT-based approaches for blind frequency offset estimation on MC-CDMA downlink. By analyzing the signal subspace structures of the MC-CDMA signals, the natures of the spreading codes and the number of users determine the feasibility of the ESPRIT-based approaches for the blind estimation task.
