The signal spectrum ise xtrapolated basing on the minimum entropy criteria to increase signalresolution .
最小熵谱外推技术是一种非参数方法。

By experiment, data is tested in the areas of improving signal to noise ratio, ameliorating signalresolution, and enhancing the processing capacity of the transient signal.
搭建实验系统，从改善系统信噪比、提高信号分辨率和增强对瞬变信号的处理能力等方面进行实验测试。
