摘要： A network multiple-input multiple-output (MIMO) wireless signal transmission and power control system includes a plurality of adjacently arranged cells. Each cell is a regular polygon and includes a plurality of adjoining sides, a base station located at a center of the cell, a plurality of directional antennas equipped at the base station, and a power adjustment unit electrically connected to the directional antennas. The directional antennas point towards connection points of the adjoining sides, and sectorize the cell into a plurality of kite-shaped sections by regarding the directional antennas as centers. The power adjustment unit controls power output of the directional antennas. By changing pointing directions of the directional antennas, the cell can be sectorized into the kite-shaped sections to significantly increase system capacity and communication quality.

摘要： The invention provides a speaker recognition method, which comprises three stages of recognition. The first-stage recognition is to detect whether a text-dependent test statement is a spoofing attack of the replay. The second-stage recognition is to detect whether a text-independent test statement is a spoofing attack of the synthetic speech. The third-stage recognition is to judge which registered speaker speaks the text-independent test statement by a speaker recognition system. If it is not spoken by the registered speaker, it is directed to an imposter. The first two stages use different features with different binary classifiers, and the third stage uses a complex classifier to determine the text-independent is spoken by target or imposter through Ensemble Learning and Unanimity Rule with conditional retry mechanism. Therefore, the rate of blocking the target can be effectively reduced without losing the rate of blocking the impostor.
