  • Method for selecting source transmit antenna in cooperative MIMO communication system
    Patent number: 8948686
    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.

  • Source antenna switching scheme for non-orthogonal protocol
    Patent number: 8699400
    Abstract: The present invention relates to a source antenna switching scheme for a non-orthogonal protocol; and more particularly, to a source antenna switching scheme for a non-orthogonal protocol, which transmits a signal of a source node to a destination node through a relay node. The present invention provides a source antenna switching scheme for a non-orthogonal decode-and-forward protocol that can acquire a greater diversity than the conventional NDF protocol. In other words, the present invention provides a source antenna switching scheme for a non-orthogonal decode-and-forward protocol that can increase a diversity order by adding a reasonable priced antenna instead of expensive hardware such as an RF chain when there are a plurality of antenna in the RF chain.
