摘要
Abstract
In consideration of class of greedy algorithm being one class of the algorithms used most widely in CS signal reconstruction, this paper gives a comprehensive comparison and analysis of four most typical algo-rithms in this class. Firstly, the four algorithms are analyzed theoretically, the relations among them compared and the corresponding implementation processes given respectively, and then the indices on measuring comprehensive-ly CS reconstruction algorithm are presented, based on which the performances of the four algorithms are entirely compared. By the theoretical analysis and simulation results, the relevant conclusions are also drawn in this paper.关键词
