摘要：
Carrier Frequency Offset (CFO) is a critical factor affecting the synchronization accuracy in Orthogonal Frequency Division Multiplexing (OFDM), and understanding its effects and developing effective mitigation strategies are crucial for achieving robust communication systems. This research investigates the model and impact of subcarrier variance on the normalized CFO density, varying length of Cyclic Prefix (CP), and the Maximum Likelihood (ML) estimation of time and frequency offset in OFDM system in the presence of Additive White Gaussian Noise (AWGN).
