    Abstract: A method for determining a performance of a MIMO communication is described comprising determining an estimate for the performance of the communication when using a first detection method, determining a measure of the orthogonality of a communication channel used in the communication and weighting the estimate for the performance of the communication when using the first detection method based on the orthogonality of the communication channel to generate an estimate for the performance of the communication when using a second detection method.

    Abstract: A wireless device includes a digital receiver configured to receive data via an antenna array, and to determine a load metric based on a load of subcarriers around reference subcarrier signals of a reference signal, and a controller configured to compare the load metric to a load threshold to determine whether the load of the subcarriers is less than a predefined level, and if the load of the subcarriers is less than the predefined level, identify at least one time point where the reference signal repeats itself during a symbol period, and control the antenna array to switch among the plurality of antenna beamforming patterns based on the at least one time point.
