| Abstract: | This paper propues anadvamed DS algorithm the paper Not only does gives the flow chart for the algorithm, but also mainly concentrates on the detailed presentation and discussion of the essential parts of the programmes grounded on the advanced DS algorithm, which are finished on my own and successfully tested in a simulation. Simulation results demonstrate that the realization of the advanced DS algorithm greatly outperforms that of traditional three-step search algorithm and has magnificently improved the efficiency with regard to compression ratio and computing speed. |
