Abstract
In this paper a new concept based on signal periodicity about AR model is presented, many problems which are difficult to be resolved in classical viewpoint such as order selection, pseudo frequency recognizing, relation determination between coefficient and signal amplitude, and relation determination between order and signal length are investigated profoundly by the new viewpoint, in the last, a sample signal is analyzed, all the results from the computation according to this method testifies that periodicity is more effective than statistical concept for AR model of signal.
