A method of selecting operation antennas in a multiple input receiver having a plurality of antennas connected to respective antenna ports of the receiver may be provided to save energy and/or other resources. The method comprises determining pairwise correlation of propagation channels among the plurality of antenna ports, respectively, determining a candidate first number of antenna ports to use for operation, selecting the first number of antenna ports among the plurality of antenna ports, wherein the selecting comprises selecting antenna ports based on mutual correlation among the plurality of antennas, and operating the multiple input receiver using the selected first number of antenna ports if there is no significant performance gain from using all of the plurality of antenna ports. A receiver, communication device and computer program for the same, as well as method, computer program and equipment for testing such a receiver are also disclosed. |
