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。
Frequency - domain equalization . at the same time discusses some key problems in ofdm : high ratio of peak - to - average power of output signals , problem of synchronization , channel estimation , adaptive bit , power and subcarrier allocation . emphasize on channel estimation , and present a new algorithm which can filtering more interpolation errors and noise . for the sake of improve the performance of resist narrowband noise and make efficient use of the spectrum apply malvar wavelet division

During the course of the research , the criterions of the interpolation effect are mean error ( me ) , mean absolute error ( mae ) , root mean squared interpolation error ( rmse ) and the difference of mean square deviation between the measured and the estimated surface air temperature . the conclusions are as follows : ( 1 ) by contrasting the gaussian weighted model associated with the error modification with the gaussian weighted model , the error modification is proved to considerably ameliorate the precision of spatial interpolation ; ( 2 ) on the base of the gaussian weighted model , taking altitudinal effect into account can reflect the trend in which temperature changes according to the topographic altitude and may ameliorate the precision of spatial interpolation correspondingly and apparently , which indicates that topographical effect on the preciseness of spatial interpolation can not be disregarded in terms of the region with complicated topography ; ( 3 ) the map of daily surface air temperature distribution , using the modified gaussian weighted model a and b , can accurately reflect the temperature - changing - with - topographical - altitude trend . among them , the better is the model a , whose me is below 0 . 03 ?
在此过程中，采用平均误差( me ) ，平均绝对误差( mae ) ，插值平均误差平方的平方根( rootmeansquaredinterpolationerror ，简称rmsie ) ，插值前后测站要素值的均方差( meansquaredeviation ,简称msd )差值作为判定插值效果的标准，得出如下结论：通过高斯权重法与结合逐步订正的高斯权重法的对比，说明结合逐步订正方案的高斯权重法可大大提高地面日气温的插值精度；在高斯权重法中加入海拔影响项可以反映出温度随地形高度的变化趋势，同时也能较大地提高地面日气温的空间插值精度，说明在地形复杂的区域，地形影响在插值精度中是不可忽略的；对于高斯权重法的两种改进方案得到的地面日气温分布图都能很好地反映出表面大气气温随地形高度的变化趋势。
