- W2383596576 abstract "Carrier Frequency Offset(CFO)of OFDM system leads to the difference between signal powers of the same sub-carrier in neighboring OFDM symbols.Thus,an improved CFO estimation method,named the Difference of Sub-carrier Power(DSP),is proposed on the basis of the characteristic that the 4th-order moment of OFDM signal is a cosine function of CFO.The proposed method has a simple close-form solution,which avoids the process of iterative searching and has less computational complexity,and it is suitable for slow time-varying frequency selective fading channels.The simulation results show that,compared with the existing methods,the proposed method provides a good trade-off between computational complexity and estimation performance." @default.
