<p>A method for implementing precoding includes the following steps: the hierarchical data which has been layer mapping processed is divided into at least two paths to be received respectively (S10); a precoding matrix is split according to the divided hierarchical data, and the split precoding matrixes are left multiplied with said divided hierarchical data respectively (S11); and the data in the corresponding location in the matrixes which are obtained by left multiplying with the divided hierarchical data respectively is added to obtain precoded output data (S12). An apparatus and system for implementing precoding are also provided by the present invention. Application of the present invention, by performing the processing of first splitting and then merging to the precoding, can use the existing platform of the transmission end in the base station, implement the precoding operation of high bandwidth and multi-antenna, save the cost, and improve the usage flexibility.</p> |
