摘要
针对智慧农业生产管理中准确定位存在的缺陷,结合Chan算法和Taylor级数展开法的优点,提出了LTE定位系统中的一种改进定位算法。该算法剔除了Chan算法中误差较大的定位结果,将优化后的结果作为Taylor级数展开法的初值,然后对这两种算法得出的定位结果进行加权求和,将最终结果作为移动设备的位置坐标。实验表明,在噪声环境中,提出的算法能有效改善定位精度,更好的为智慧农业生产服务。
Against the defects existing in accurate positioning of production management in wisdom agriculture,and combining the advantages of Chan algorithm and Taylor series expansion method,the article has proposed an improved localization algorithm in the LTE positioning system.The algorithm eliminates much deviation of the positioning results in Chan algorithm,offers the optimized result as the initial value of Taylor series expansion method,then get the weighted sum of the positioning of the results of the two kinds of algorithm,finally put the final result as the location of the mobile devices coordinates.Experimental results show that the proposed algorithm can improve the positioning precision effectively in the noise environment,and sever the wisdom agriculture better.
