Some aspects regarding radio resources management in multi-antenna systems

In this paper, multi-antennas transmission techniques, based on spatial multiplexing and space diversity, are considered as means to enhance the performance of WLANs systems. Link adaptation is introduce in order to determine the most appropriate PHY configuration in terms of achievable throughput and error performance, for different configuration of transmit and receive antennas, modulation scheme and coding rates. The physical layer parameters selection is done according to the application requirements, in the attempt to efficiently use the available radio resources.
