摘要：
Disclosed is a method for static power allocation to source and relay stations in a two-hop amplify-and-forward (AF) relay multi-input-multi-output (MIMO) network including of a source station (SS), a relay station (RS), and a destination station (DS) each transmitting signals using multiple antennas. The method performs power allocation to the SS and the RS according to the path loss, or equivalently, according to a distances, between the SS and the RS and the RS and DS. The transmit power of each transmit antenna at the SS and the power amplifying gain of the RS are determined from the power allocation outputs.
