摘要： Embodiments are directed to a link adaptation method that selects the optimum transmission scheme and modulation and coding signal (MCS) level within a MIMO system, based on optimal maximum throughput on the channels. The method selects the MCS levels and spatial rate values for broadband communication systems based on the instantaneous broadband MIMO-OFDM signaling capacities. The transmission rate over the transmission channel is selected based on a comparison of the capacities achieved under diversity coding and spatial multiplexing MIMO transmission schemes. The effect of a particular receiver type or implementation can also be factored into the signaling capacity. For a fixed target probability of error, the scheme or spatial rate that has the higher instantaneous throughput is selected for transmission.

摘要： Systems and methods for optimizing transmission of a plurality of data streams on a multiple-input multiple-output channel are described. The systems and methods for optimizing reduce the multiple-input multiple-output channel for each transmission scheme to an equivalent single-input single-output channel for the transmission scheme and transmit the plurality of data streams based on the single-input single-output channel for the transmission scheme. Systems and methods for optimizing the transfer of data for any number of transmit and receive antennas are described.
