摘要：Orthogonal frequency division multiplexing system is multichannel system that provides high rate and high quality wireless communication services, but system performance is degraded by two factors, one is the symbol timing offset (STO) and other is the carrier frequency offset (CFO) caused by Doppler frequency shift. Several approaches have been proposed to estimate time and frequency offset. Most frequency and timing estimation methods use the periodic nature of the time domain signal by using a cyclic prefix or by designing the training symbol having repeated parts. In this paper, the effects of STO and CFO in OFDM system have been studied. Also, the estimation techniques to handle the STO and CFO problems in OFDM system by using cyclic prefix and training symbol has been analyzed
