插值權
  • interpolation : 補入
  • weight : n 1 重量；體重；求心力，重力，（地心）引力。2 斤兩，分量，衡，計重單位。3 （壓東西的）重物。4 砝...
  1. 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。
  2. For h - d scattered data, local weighted least - squares fitting ( llsf ) methods for approximation and interpolation are respectively put forward and the latter is got by adjusting weight function in the former case, and the interpolating method is also used to construct hyper - surface models with the radial function. the problem of choosing weight function during local least square approximation is discussed and two good weight functions are given : one with a parameter, the other with no parameter. based on them

    二、對非規則區域上分佈的h - d數據，提出了散亂數據超曲面擬合的局部最小二乘逼近法。通過對局部最小二乘逼近的權因子作適當的改進，得到了擬合精度較高的局部最小二乘插值法，還用徑向基函數構造了超曲面模型，找到了一種性質好帶參數的權函數以及另一種有著普遍精度性質的不含參數的權函數，獲得了較好的逼近效果。
  3. Furthermore, unlike other algorithm, it is free of the definition of weight and estimation of parameters in order to get a realistic image, it is necessary to do processing works, such as transform of plot, hidden - line elimination, illumination, texture mapping, to the 3d models constructed through interpolation

    通過插值建立它的三維模型后，要得到真實感圖像，還必須對三維模型施以繪圖變換、消隱、光照、紋理映射等處理。
  4. Moving least squares interpolants do not pass through the data because the interpolation functions are not equal to unity at the nodes unless the weight functions are singular

    但是，移動最小二乘法的近似函數不一定精確地通過計算點，除非使用奇異的權函數。
  5. Moving least square interpolants do not pass through the nodes because the interpolation functions are not equal to unity at the nodes unless the weight functions are singular

    在用移動最小二乘法構造形函數時，只需在求解的區域內布置一系列的節點，而不需要劃分網格。
