Abstract

In a method for identification of a multiple antenna transmission mode in a radio receiver, at least two antenna-decoupled data streams (s0, s1) are produced by means of an antenna decoupling unit in the receiver. Respective first variables (p0, p1) are calculated for both data streams, and are dependent on the phase change between the data in the respective data stream. An evaluation unit uses these first variables as the basis to decide whether a multiple antenna transmission mode is being used in the transmitter.
