例句与造句
- The problem of doa ' s estimation of multiple source signals incident on a arbitrary array in the presence of both unknown spatially correlated noise and sensor errors is firstly considered . a modified ml estimation of doa ' s and sensor gain errors is presented . unlike previous work , the proposed method does not impose any structure constraints or parameterization of the signal and noise covariances . the algorithm can be carried out via the alternating projection approach . finally , the performance of the proposed method is shown with computer simulations as well as real array data
在空间相关色噪声环境及存在阵列模型误差情况下，首先给出了基于最大似然的doa及阵列幅相误差联合估计算法，该算法对信号和噪声无任何约束，且适用于任意阵列结构。算法可以利用交替投影迭代搜索实现，计算机仿真实验和外场实测数据表明，本章算法能给出比传统的最大似然方法更高的估计性能。 - First , the theories of the music algorithm and the esprit are presented here . conventional algorithms are limited by the array configuration , and a constructing vectors algorithm , which uses the correlative function of array data , is proposed in this paper . this algorithm is n ' t restricted within the special array configuration , and it is also very steady
在介绍了多重信号分类( music )算法和旋转不变技术( esprit )的基本原理后,考虑到常规的算法都受到阵列形式的限制,本文在esprit算法的基础上,提出了一种利用阵元数据的相关函数构造向量的算法,该算法不要求特定阵列结构,且有一定的稳健性。 - Chapter three describes the uneven development of regional economy utilizing many time array datum and cross section datum . afterwards , the regional difference of the location of fdi and its affecting factor is analyzed . chapter four chiefly studies the effect of fdi on regional economic growth from two aspects named theoretic analysis and positive analysis
本章利用大量的时间序列和横断面数据资料，分别从地区经济总量、经济发展水平、发展速度和fdi总量、地区分布绝对差距和相对差距方面描述了中国引进fdi与区域经济的不平衡特征，进而对导致这种区域不均衡分布的原因进行了剖析。 - It's difficult to find array data in a sentence. 用array data造句挺难的
