Abstract
A method is provided for adapting a multi-antenna transmission from a first node to a second node over a wireless channel. A wireless channel has at least three inputs and at least one output. The first node and the second node are included in the wireless communication system. The method includes obtaining (401) at least one symbol stream; Determining (403) a precoding matrix having a product structure generated by multiplying the block diagonalized matrix by the block diagonalized unitary matrix to the left of the block diagonal matrix; Precoding (404) at least one symbol stream with a determined precoding matrix; And transmitting (405) the precoded at least one symbol stream to a second node over a wireless channel.
Multi-antenna transmission, block diagonalized unitary matrix, block diagonal matrix, precoding, product structure
