Abstract
Disclosed is a method for selecting a source transmit antenna in a cooperative multiple-input and multiple-output (MIMO) communication system including a source node, a relay node and a destination node. The method includes determining a source transmit antenna selection metric such that a source-destination channel, a source-relay channel and a relay-destination channel are related to one another, and selecting a positive integer number of antennas such that the source transmit antenna selection metric is maximized.

A method for selecting a source transmit antenna in a cooperative multiple-input and multiple-output (MIMO) communication system comprising a source node, a relay node and a destination node, the method comprising:
- setting a source transmit antenna selection metric such that a source-destination channel, a source-relay channel and a relay-destination channel are related to one another;
- and
- selecting a positive integer number of antennas such that the source transmit antenna selection metric is maximized,
- wherein the source transmit antenna selection metric is set using a minimum value of a sum of square of each element of channels formed from a source node antenna and receive antennas of a destination node, a minimum value of a sum of square of each element of channels formed from a source node antenna and receive antennas of a relay node, and a minimum value of a sum of square of each element of channels formed from a relay node antenna and receive antennas of a destination node.
A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising program code instructions for:
- setting a source transmit antenna selection metric such that a source-destination channel, a source-relay channel and a relay-destination channel are related to one another;
- and
- selecting a positive integer number of antennas such that the source transmit antenna selection metric is maximized,
