Abstract
A method in a first node (100) to adapt a multi-antenna transmission to a second node (120) on a wireless channel (130), the wireless channel (130) having at least three inputs and at least one output, the first node being (100) and the second node (120) comprised in a wireless communication system (110), the method comprising the steps of: obtaining (401) at least one stream of symbols, determining (403) a pre-coding matrix that it has a product structure in which the product structure can be broken down into a matrix of block diagonal that is multiplied from the left with a unit matrix of block diagonalization, pre-encoding (404) the at least one stream of symbols with the pre-coding matrix determined, and transmitting (405) the at least one pre-encoded stream of symbols over a wireless channel (130) to the second node (120).
