摘要

匹配滤波目前用于重复信号与同步平均得到的模板之间的时延估计。我们提出了用信号平均法估计模板对最终平均信号的影响分析。我们给出了一个充分条件，该条件必须通过平均过程中出现的抖动来验证。这个条件通常在实践中得到验证，足以避免有偏差的结果。用无噪声高斯信号的仿真来说明这种干扰效应。

Alignment process using correlation influence of template estimation

Matched Filtering is currently used for Time Delay Estimation between a repetitive signal and a template obtained by synchronous averaging. We propose an analysis of the effect of the estimation of the template by signal averaging on the final averaged signal. We give a sufficient condition which has to be verified by the jitter occuring in the averaging process. This condition often verified practically is sufficient to avoid biased results. The disturbing effect will be illustrated by simulation using a noiseless gaussian signal.
