This article analyzes the relationship between the spectrum energy leakage and the interceptive position under non-integer-period truncation,and proposes a criterion of the smallest energy leakage that can be used as a rule of period estimation.

In such averaging based on digital computers, the period actually used usually possesses some errors, here called period cutting error, which is.

Error analysis for electrical power measurements with non-integer-period sampling;

The Non-Integer-Period Sampling Theory for Periodic Siqnals;

In the signal distortion measurement based on DFT, the technique can effectively minimize the spectrum leakage caused by the non-integer-period sampling.

By analyzing the Hamming weight distribution on different puncturing points due to puncture period, this paper revealed the importance of puncture period, and got to the conclusion that puncturing period was a key factor responsible for the improvement brought by puncturing pattern selection.

In the simulative match of Robocup, when a having-ball player wants to kick the ball to a direction, the prediction of the possible interceptive cycles of other players after the ball is kicked out has an extremely important impact on the decision making of having-ball player.
