Abstract
A method for implementing precoding includes the following steps: dividing hierarchical data which has passed through layer mapping processing into at least two paths to be received respectively (S); splitting a precoding matrix according to the divided paths of hierarchical data, and respectively left multiplying the split precoding matrixes with the divided paths of hierarchical data (S); and adding the data of corresponding bits of the matrixes obtained by respectively left multiplying with the divided paths of hierarchical data, to obtain precoding output data (S). The present invention also provides an apparatus and a system for implementing precoding. The present invention, by performing the process of splitting firstly and then combining to the precoding, can realize the precoding operation with large bandwidth and multi-antenna by using the existing platform at the transmitter of the base station, thereby saving the costs and enhancing the usage flexibility.
