OFDM (Orthogonal Frequency Division Multiplexing) is a promising technique for 4G and 3GPP LTE system in terms of providing the higher data rate and efficient use of bandwidth. But OFDM suffers from ISI and ICI interferences in wireless and fading environment. There is a loss of certain amount of data because of these interferences, thus synchronization is required. It is important to estimate and correct the start of OFDM symbol efficiently to reduce timing and frequency offset errors. The paper mainly focus on the CFO problem present in OFDM system, describes the effect of CFO in OFDM system and provides the estimation techniques for CFO in time domain and frequency domain. The simulation results are performed for the CFO estimation technique with different values of CFO and then results has been compared.
