插值误差 meaning in Chinese
interpolation error
Examples
- We have improved the method of anisotropic interpolation error estimations and presented a method to estimate the consistent errors of nonconforming elements
我们改进了各向异性插值误差估计的判定方法，并给出非协调元的相容误差的各向异性误差估计的方法 - Among them a pel and dobrowoiski have published a series of papers deal with anisotropic lagvangc interpolations . however , the studies on the estimations of consistent errors for nonconforming elements have been seldom reported
如t . apel等学者给出了lagrange元的各向异性插值误差估计，但对非协调元的相容误差的各向异性误差估计在文献中尚无报道。 - This paper introduces a bispectrum - based channel estimation algorithm to improve the accuracy of the channel estimation at pilots and proposes an equalization method with the view of the reduction of the interpolation error
为了提高信道估计的精度，本文分别从提高导频处信道估计精度和减小插值误差的角度出发提出了基于导频双谱的信道估计算法和基于变换域滤波的插值方法。 - 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,论文在ofdm系统的信道估计方面,先对基于导频的ofdm信道估计中的多种插值方法进行了分析,讨论了噪声对插值精度的影响,指出插值本身的精度所造成的插值误差远大于噪声所带来的插值误差,从而阶次更高的插值算法在实用中并非最优的;并指出插值滤波法比变采样率算法对噪声的影响更为敏感,在信噪比较高时插值滤波算法比变采样率算法更优。 - Using our method we have presented the anisotropic estimations of both interpola - tion errors and consistency errors for these two elements . quasi - wilson ' s element is a nonconforming element for arbitrary quadrilateral meshes . we have proved that the quasi - wilson element is anisotropic - convergent for narrow quadrilateral meshes
