Abstract
A resource allocation strategy of low computational complexity is proposed that aims at maximising the sum rate while providing minimum rates in a MIMO-OFDM broadcast system. Therefore, two users per carrier are assigned and all eigenvalues of the scheduled users are served by means of beamforming techniques. For each carrier the power distribution between the two users is adapted finally. The algorithm is evaluated by means of simulation results.
