摘要: A method in a first node for adapting multi-antenna transmission to second over wireless channel is provided. The has at least three inputs and one output. the are comprised communication system. comprising steps of: Obtaining (401) symbol stream; Determining (403) precoding matrix having product structure created by block diagonal being multiplied from left with diagonalizing unitary matrix; Precoding (404) stream determined And Transmitting (405) precoded node.
