Abstract

Propose two align methods and improvements for signals from the same source whose relative position is unknown, which based on signal energy and signal similarity respectively. In this paper, algorithms were discussed in detail and through extensive testing on speech signal algorithm to improve and detailed analysis. Experimental tests indicate that, the method of iterative synchronize alignment can improve the computational efficiency in the premise of meet the accuracy requirements, makes it possible to applied to small devices such as embedded devices.
