Abstract
A fine symbol timing synchronization method and apparatus in an orthogonal frequency-division multiplexing (OFDM) system are provided. The fine symbol timing synchronization method finds a path with a minimum mean square error (MMSE) as a first path among a plurality of paths, and a formula of the mean square error (MSE) used by the method is a simplified formula of the original MSE formula with low calculation complexity. Therefore, the time required by the fine symbol timing synchronization method is short, and a correct first path can be found, so as to lock a starting position of a fast Fourier transform (FFT) window on a starting position of a symbol signal of the correct first path.
