sparse signal decomposition 稀疏信号分解
In the third chapter, a measure of frequency estimation based on signal sparse decomposition is introduced.
在第三章中，介绍了基于信号稀疏分解的频率估计方法。
We will improve the speed of seismic signal sparse decomposition in the case of that the quality of the reconstructed signal is ensured.
因此本论文将对蚁群算法和蒙特卡罗方法进行研究，在保证重建信号质量的前提下，提高地震信号稀疏分解的速度。
Otherwise, signal sparse denotation and decomposition can not be practical, it can only remain in the searching phases.
为促进信号稀疏表示、稀疏分解的研究与应用，研究其快速算法是十分必要的。
