| 摘要 |
The present invention provides a data transmission method, a transmitter, and a receiver in a coordinated communication system, including: precoding, by a first transmitter, its payload data by using a first precoding matrix to obtain first precoded data; precoding, by the first transmitter, coordinated data by using a second precoding matrix to obtain second precoded data to cancel interference with the first precoded data at a receiver caused by data transmitted by another transmitter; and transmitting the first precoded data and the second precoded data after the precoding to the receiver. According to the method, the first transmitter codes its payload data by using the first precoding matrix; and codes the coordinated data by using the second precoding matrix to cancel, by using different precoding matrices, the interference with the first precoded data at the receiver caused by the data transmitted by another transmitter.
