Abstract

The invention concerns a method for determining communication channel characteristics in a MIMO communication system, the system comprising at least one transceiver A having N antennas and at least one transceiver B having N antennas, the system using at least a first communication channel HAB from A to B and a second communication channel HBA from B to A. The method is distinguished in that it includes steps for rendering the communication channels HAB and HBA identical by the use of precoding. The invention also concerns a transceiver and a MIMO communication system implementing the method of the invention.
