The Research of A New Robust Wireless Location Algorithm

本文提出了一种新的稳定的无线定位算法。该算法以SNR为理论基础,计算出最佳的子相关长度,从而保证了TOA获取的稳健性。同时在针对传统最小二乘在收敛方面的局限性,借鉴marquardt算法对其进行改进,提高了定位的成功率和定位精度。从仿真的结果可以看出,无论在理论上,还是工程上,该算法对于无线定位系统的实现具有一定的参考价值。

The paper proposes a new robust wireless location algorithm. The algorithm computes the optimal sub-correlation length using SNR as theory foundation, So the robust of TOA would be guaranteed. And For the limitation of convergence about the traditional least-square algorithm, the algorithm uses marquardt algorithm for conference and overcome the limitation. So the success rate and the location accuracy would be improved. From the result of simulation, the algorithm has a good value about the realization of wireless location system in theory and engineering field.
