  1. You invoke an operator procedure implicitly by using the operator symbol in an expression

    使用表達式中的運算符符號隱式調用運算符過程。
  2. Secondly, the dissertation proposes a novel blind symbol - timing scheme for ofdm systems based on cyclostationarity feature of received symbols. the proposed schemes also exploits the periodicity of ofdm symbol introduced by cyclic prefix, by applying 2 - dimentional fourier transformation and choosing the appropriate correlation peak value as the symbol start location, the precision of this scheme is higher than previous conventional method. thirdly, the dissertation presents analysis with regard to channel estimation of ofdm systems. several interpolation algorithm in ofdm systems which based on pilot sequence have been analyzed in the first instance, and the influence of the channel noise on interpolation precision has discussed. the theoretic analysis and simulation results show that : the interpolation error induced by the precision of interpolation procedure itself has out weight

    第三，論文在ofdm系統的通道估計方面，先對基於導頻的ofdm通道估計中的多種插值方法進行了分析，討論了噪聲對插值精度的影響，指出插值本身的精度所造成的插值誤差遠大於噪聲所帶來的插值誤差，從而階次更高的插值演算法在實用中並非最優的;並指出插值濾波法比變采樣率演算法對噪聲的影響更為敏感，在信噪比較高時插值濾波演算法比變采樣率演算法更優。
  3. Declares the operator symbol, operands, and code that define an operator procedure on a class or structure

    聲明在類或結構上定義運算符過程的運算符符號、操作數和代碼。
