The　cyclostationarity　property　of　the　OFDM　signal　embedded　pilots　is　examined　based　on　the　theory　of　cyclostationarity.　The　final　conclusion　of　this　paper　can　be　used　as　the　basis　of　the　cyclostationarity-based　blind　algorithms.　Mathematical　deduction　and　simulation　results　both　show　that　if　the　received　signal　embedded　pilots　are　sampled　at　the　data　rate,　a　cyclostationary　sequence　can　be　obtained.　And　the　cyclic　period　of　the　sequence　equals　the　length　of　the　OFDM　symbol.
