Abstract

Abstract:

In burst-mode communication systems, considering the great influence of the residual frequency offset on the phase estimation in joint frequency-phase estimation, the symmetry decoupling technique is proposed. First, the characteristic is analyzed that the symmetrical set of sampling instants can decouple the joint frequency-phase estimation. Then the concept of symmetry decoupling technique is proposed. Second, the symmetry decoupling technique is applied to the joint frequency-phase estimation under both the data-aided mode and non-data-aided mode. Also, the relative theoretical analysis is given. On this basis, the concepts of serial/parallel joint frequency-phase estimators are proposed. Theoretical analysis and simulation results show that the structure processed by the symmetry decoupling technique can achieve a lower mean square error and improve the ability to tolerate the residual frequency offset by three times at least. Besides, the proposed technique has universality which can be applied to other joint frequency-phase estimation algorithms.
