中文摘要：
为了提高Gabor表示的时频分辨率,使用了基于度量函数的窗函数宽度自适应选择算法,并利用其优化后的Gabor时频分布在时频联合域内运用时频掩蔽技术进行滤波,用于非平稳信号的中分量提取或降噪。实验结果表明了改进的自适应离散Gabor变换算法在信号处理中的有效性和实用性。
英文摘要：
This paper proposed an adaptive algorithm for Gabor transform which improved the time-frequency resolution with higher practicability and adaptability. It presented a time-frequency filter on the joint time-frequency plane based on its excellent time-frequency distribution and time-frequency masking,which could used to extract signal components and denoise. The experimental results showed that the filter based on adaptive Gabor transform is effective and practical in signal processing.
