Fine frame synchronization

This study focuses on fine frame synchronization methods in Orthogonal Frequency Division Multiplexing (OFDM) systems, with an emphasis on Maximum Correlation techniques. The research, supervised by Dr. Chao-Yung An and conducted by student Chen Ying-Jun, analyzes the effectiveness of synchronization in varying Signal-to-Noise Ratios (SNR), including simulations at SNRs 10, 20, and 30. It aims to evaluate the Mean Square Error (MMSE) and provides insights on performance across different environments, concluding that high SNR is essential for successful synchronization.
