摘要： A method for testing wireless performance of a MIMO wireless terminal includes: obtaining antenna pattern information of a plurality of antennas of the MIMO wireless terminal tested in an electromagnetic anechoic chamber; further obtaining a test signal according to the antenna pattern information of the MIMO wireless terminal; calibrating the test signal by using an error calibration joint matrix of the MIMO wireless terminal so as to obtain a transmitting signal for testing; and finally feeding the transmitting signal for testing into a plurality of measurement antennas of the electromagnetic anechoic chamber and transmitting the transmitting signal to the wireless terminal through the measurement antennas so as to test the wireless terminal. As the transmitting signal for testing is obtained by calibrating the test signal with the error calibration joint matrix, a test error is eliminated, thus solving a technical problem in the related art that the test error cannot be quantified such that the accuracy and repeatability for testing the MIMO wireless terminal are affected.

摘要： A method and apparatus for improving a performance of a system. An influence network is generated for an array of elements in the system using a reconfiguration algorithm. The influence network indicates an influence of an undesired event occurring at any element in the array of elements on a remaining portion of the array of elements given a current state of the array of elements. A relative ranking of vulnerability is created for elements in the array of elements based on the influence network. The reconfiguration algorithm is modified to take into account the relative ranking of vulnerability to form a modified reconfiguration algorithm. The system using the modified reconfiguration algorithm to compensate for undesired events improves the performance of the system.
