Abstract:
1. A multi-layer beam forming method, comprising: according to an obtained transmitting weight value of each space channel layer, obtaining a signal-to-noise ratio of a data stream, arriving at a receiving side, of each space channel layer; according the obtained signal-to-noise ratio of the data stream, arriving at the receiving side, of each space channel layer, determining a data stream which is able to be transmitted; performing beam forming for the data stream which is able to be transmitted and transmitting the data stream subjected to the beam forming to the receiving side; wherein a process of determining the data stream which is able to be transmitted according to the obtained signal-to-noise ratio of the data stream, arriving at the receiving side, of each space channel layer comprises: comparing the obtained signal-to-noise ratio of the data stream, arriving at the receiving side, of each space channel layer and a preconfigured signal-to-noise ratio threshold, and determining that a data stream, whose signal-to-noise ratio when the data stream arrives at the receiving side is greater than the signal-to-noise ratio threshold, of each space channel layer is the data stream which is able to be transmitted.
