Considering the impact of the joint frequency-phase offset estimation frequency error on the phase offset estimation in short burst communication systems

a symmetrical frame structure is introduced.First

based on a generalized (asymmetrical) frame structure we give a concept of the symmetrical frame structure and then develop the corresponding data-aided (DA) and non-data-aided (NDA) Cramer-Rao Bounds (CRBs) for the carrier parameter estimation.Then

according to the above CRB characteristic a joint frequency-phase offset estimation is proposed using the symmetrical frame structure.Taking the maximum likelihood (ML) based joint frequency-phase offset estimation for an example

simulation results show that the phase offset estimation based on the symmetrical frame structure can achieve lower mean square error (MSE) and have better ability against the large frequency offset compared with the phase offset estimation based on the asymmetrical frame structure.
