The present disclosure provides a symbol synchronization method and apparatus. By means of the symbol synchronization method and apparatus, a timing location is adjusted outside an adaptive loop. In addition, the adaptive loop proceeds to according to an original function of the adaptive loop. That is, the timing location is stabilized to an initial symbol-synchronization location, and the timing location is then further corrected and adjusted. Therefore, impact of an error of a timing location on symbol synchronization is eliminated by correcting the timing location, and positioning accuracy of a symbol-synchronization location is improved.
