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. -
