Application of space spectrum estimation technique based on MUSIC algorithm in TD-LTE uplink timing

空间谱估计算法因其在参数估计方面具有分辨性能高、稳健性好等优点被广泛应用。为提高Td-lTE低信噪比时定时的准确度,提出一种基于空间谱估计的定时偏移估计算法,利用Td-lTE上行特殊的导频结构,构造出与空间谱估计相类似的模型,利用MuSIC算法进行定时偏移估计。仿真结果表明,即使在信噪比很低的情况下,基于MuSIC的定时偏移估计算法的估计性能依然很好。与传统的算法相比,存在多径的情况下,基于空间谱估计技术的定时准确度大大提高。The spatial spectrum estimation algorithm was widely used at the aspect of the parameter estimation because of its many advantages such as higher resolution,greater robustness and so on.In order to improve the timing accuracy at low sig nal-to-noise ratio(SNR)of TD-LTE,a kind of timing offset estimation algorithm based on the spatial spectral sstimation was presented.By the special pilot structure of TD-LTE uplink,a model which is similar to patial spectrum estimation can be built and then use MUSIC algorithm to get the timing offset estimation.The simulations reveal that,the estimation performance is very good even in the case of low signal-to-noise ratio.Compared with the traditional algorithm,the timing accuracy will greatly improve when use a technology which is based on spatial spectral estimation algorithm.国家自然科学基金项目(61201192):基于时频域耦合的分布式MIMO信道建模; 重大专项项目(20122X03003007-004)支持:基带集中处理的RAN构架研究; 973项目(2012CB316000); 无线移动通信国家重点实验室(电信科学技术研究院)合作项目(20122000153):认知无线电中的动态频谱分配技术研

以砂纸为模板制作聚合物超疏水表面

报道了一种聚合物材料超疏水表面的简便制备方法.以不同型号的金相砂纸为模板,通过浇注成型或热压成型技术,在聚合物表面形成不同粗糙度的结构.接触角实验结果证明,聚合物表面与水的接触角随着所用砂纸模板粗糙度的增加而加大,其中粒度号为W7和W5砂纸制作的表面与水的接触角可超过150°,显示出超疏水性质.多种聚合物使用砂纸为模均可制备不同粗糙度及超疏水的表面,本征接触角对复制表面浸润性的影响从Wenzel态到Cassie态而变小.扫描电镜结果表明,不规则形状的砂纸磨料颗粒构成了超疏水所需要的微纳米结构的模板
