模板与等级匹配
Template Matching with Ranks
摘要:
我们考虑的问题匹配的模板噪声信号。受信号处理文献中最近提出的一些建议的启发,我们提出了一种基于秩的方法,并使用经验过程理论中的一些成熟技术结合Hájek的投影方法来研究其渐近性质。由此产生的估计的移位示出,以实现参数的收敛速率和渐近正态。一些数值模拟证实了这些发现。
英文摘要:
We consider the problem of matching a template to a noisy signal. Motivated by some recent proposals in the signal processing literature, we suggest a rank-based method and study its asymptotic properties using some well-established techniques in empirical process theory combined with Hájek's projection method. The resulting estimator of the shift is shown to achieve a parametric rate of convergence and to be asymptotically normal. Some numerical simulations corroborate these findings.
