Conventional frequency offset estimation algorithms require high computational complexity and redundant memory. In this paper, we propose a simple carrier synchronization algorithm which can jointly estimate the frequency and phase offset, and compare the performance of the proposed algorithm with that of other algorithms. The proposed algorithm requires no hardware memory. Computational complexity of the proposed algorithm is low. The principle of the proposed algorithm is based on frequency domain analysis and interpolation technique. The proposed algorithm is asymptotically unbiased, according to the numerical derivation. Simulation results show that the estimation accuracy of the proposed algorithm is close to the CRB even when Eb/No is as low as 0dB.
