摘要：
The Systems using Orthogonal Frequency Division Multiplexing (OFDM) suffer with carrier frequency offset (CFO) results in inter carrier interference (ICI) due to which there will be large performance degradation. The impairment like CFO is caused due to mismatch of carrier frequency at the transmitter to local oscillator frequency at the receiver, multipath and Doppler shift. This paper presents a modified preamble structure based approach for CFO compensation in an OFDM systems which mitigate the effect of inter carrier interference and its equivalent energy loss. Theoretical analysis and simulation results substantiate the importance and advantages of proposed CFO compensation approach. This proposed method provides a considerable signal to noise ratio gain on bit error rate performance.
