Abstract :
In this work an efficient low-complexity user selection algorithm for the multiuser MISO downlink wireless channel is presented. The algorithm combines Zero-Forcing linear precoding with low-complexity correlation-based Space Division Multiple Access (SDMA) and aims at maximizing the sum rate of all system users. The complexity of the algorithm is analyzed and is shown to be lower than previously proposed schemes. Moreover, simulation results indicate that the performance penalty is small.
