THE ANALYSIS OF THE RESOLUTION CHARACTERS OF RELAX ALGORITHM
-
摘要: 本文讨论了RELAX算法实现信号分离的数学机理以及实现信号分辨的一些特性,探讨了这些特性对其实现信号分辨与否的表现;而且对从DD-RELAX到CD-RELAX、ELAX-AS以及MD-RELAX的发展和联系作了分析讨论。最后对所作理论分析进行了计算机模拟。Abstract: The paper gives a detail analysis of the mathematical principle of the RELAX algorithm that separating and resolving the signals, and the performance of the characters of the separation and resolution in the circumstance that the algorithm resolves the signals or not. The relationship and development of the algorithm from DD-RELAX to CD-RELAX, RELAX-AS and MD-RELAX are also discussed. The computer simulation are made to confirm the theory analysis.
