Abstract: The method of blind source separation of signal about cyclostationary is to retrieve unknown source signals from a set of samples, without necessarily having any prior knowledge about the sources. Blind source separation of mixed signals about cyclostationary is studied. In the separation process, the degree of cyclostationary is proposed as the separation criterion. The separation criterion depends on the rotation variable only and the optimal rotation angle is maximizing the combined criterion. The algorithm of the separation criterion is validated. There lies in three respects. First, the criterion by a case is proved. Second, a set of simulated data is analyzed to validate it. Third, the signals which are recorded on the experimental test gearbox are used to validate the algorithm. The results demonstrate that the algorithm is useful for the analyzing of signals about cylcostationary.
