查询词典 Welch

According to the results of comparison between these methods of spectrum evaluation, a new method of power spectrum evaluation of welding arc sound is advanced by means of association of wavelet packet analysis with the Welch average method .

对试验系统采集到的焊接电弧声进行了小波包多层分解，并利用周期图法、Welch 平均法及AR模型法，对各频段信号进行功率谱估计。根据不同谱估计方法的对比结果，提出小波包分解结合Welch 平均法对焊接电弧声进行功率谱估计的新方法。通过对几种规范与飞溅率下的电弧声功率谱的初步分析，发现其功率谱分布具有一定的规律性，并且不同频段谱峰值及其对应频率与焊接飞溅具有相关

Because the collections of observations corresponding to different states are mutually disjoint, the parameters of the models can be estimated by a sequence matching algorithm which is much simpler than the classical Baum-Welch algorithm. This reduces the computational complexity to a great extent.

由于模型中各状态对应的观测值集合互不相交，模型训练中采用了运算量较小的的序列匹配方法，与传统的Baum-Welch算法相比，大大减小了训练时间。

Due to existing signal processing technology's shortage such aslow measurement, narrow measurement range precision and other poor performance, we introduced a high-precise signal processing technology:firstly,to get power spectrum with Hanning windowed Welch modified periodogram, search its peak value frequency;secondly, to apply zooming analysis via Goertzel algorithm;at last,to get a highly precise doppler frequency with energy centrobaric rectifying algorithm.

针对存在的缺点，本文提出了一种应用于激光多普勒测速的高精度信号处理技术，即首先利用加Hanning窗的Welch修正周期图算法得到信号功率谱，搜索其谱峰值频率，接着利用Goertzel频谱细化算法对搜索的谱峰进行细化分析，再引入能量重心频谱校正算法对细化后的谱峰进行校正分析，从而将离散频谱分析算法、频谱细化算法和频谱校正算法三者有机结合起来，充分发挥各自的优点：通过加Hanning窗的Welch修正周期图算法快速得到功率谱及峰值频率，通过Goertzel算法获得分析频带的高分辨率频谱，然后通过能量重心校正算法对细化后的频谱进行高精度校正，这样不仅保证了算法的高效性，而且大大提高了分析的精度。
