A method and device for managing the use of antennas in a multiple antenna wireless transmission system for OFDM signals. The method includes defining a utility function which comprises a performance metric for transmission. Combinations of antenna and OFDM subcarriers are selected to optimize the utility function under two constraints. The first constraint is that the combinations of antenna and subcarrier include only one antenna for each subcarrier, the second constraint is that the combinations include the same number of subcarriers for each antenna.
