Considering high-speed mobile communications

transceivers always work subject to the large Doppler shift and limited pilot overhead

which severely influences the overall performance of traditional carrier synchronization pattern (TCSP). Thus

a strong robust carrier parameter estimation decoupling technique (CPEDT) is proposed

followed by its application to the TCSP (yielding the CPEDT-TCSP). First

the pilot signals with certain length are selected at receiver to perform the demodulation operation

and then the correlation operation with an effective delay length

α

is perfor

med by the demodulation signals. On the one hand

the frequency offset is estimated by the result of the correlation operation

and on the other hand the conjugate form of the correlation operation result which takes α as half of the pilot length

α

is used to implement maximum likelihood (ML) phase offset estimation. Theoretical analysis and simulation results show that considering a modified data frame

the CPEDT-TCSP can implement the decoupling between both the frequency offset estimation and phase offset estimation in the TCSP

and can also reduce the complex multiplication operations for the ML phase offset estimation.
