求翻译：由于设备上的限制，采用了2003年BCI数据竞赛Graz大学所采集到的信号，使用小波分析的方法来进行去噪处理，并对其中阈值的选择方式和阈值的作用方式进行了比较，选用全局阈值及硬阈值的作用方式消噪效果最好。是什么意思？

Due to equipment limitations, bci data race graz University in 2003 collected signal, using wavelet analysis method to denoising, and threshold selection method and the threshold of the mode of action compared mode of action of selected global threshold and hard threshold denoising.

Due to equipment constraints, with the 2003 DATA RACE BCI Graz University acquired the signal using a small wave, and methods of analysis for cleanup, and the one with the choice of thresholds and the threshold value for the mode of action is to use global threshold and hard threshold value of the m

Because on the equipment limit, used in 2003 the BCI data to compete the signal which the Graz university gathered, the use wavelet analysis method carried on denoising processing, and has carried on the comparison to threshold value choice way and the threshold value function way, selected the over

Due to the restrictions on the device, using a BCI data race 2003 year signals collected by the University of Graz, denoising using Wavelet analysis method to handle, and the choice of thresholds and threshold effects are compared, selected global hard threshold and threshold denoising based on mode
