摘要： There is provided mechanisms for adjusting an antenna arrangement for mitigating interference in a line of sight multiple input multiple output system. The antenna arrangement comprises at least two antennas. A method comprises adjusting a distance between two antennas of the antenna arrangement by an adjustment distance to compensate for interference caused by at least one reflection occurring along a line of sight link from the antenna arrangement to antennas intended to communicate with the antenna arrangement.

摘要： The present disclosure relates to a radio receiver, a radio transmitter, and methods for evaluating multiple-input multiple-output, MIMO, antenna deployment. The method for evaluating MIMO, antenna deployment comprises the steps of receiving a first composite signal via a first receive antenna. The first composite signal comprises a first tone transmitted from a first transmit antenna at a first variable frequency and a second tone transmitted from a second transmit antenna at a second variable frequency different from the first variable frequency, and also receiving a second composite signal via a second receive antenna. The second composite signal comprising the first tone transmitted from the first transmit antenna and the second tone transmitted from the second transmit antenna. The method also comprises determining a first power signal from the first composite signal, and determining a second power signal from the second composite signal, as well as determining a phase difference between the phase of the first power signal and the phase of the second power signal, and evaluating MIMO antenna deployment based on the determined phase difference.

摘要： A method for predicting the performance of a Line-Of-Sight, LOS, multiple-input multiple-output, MIMO, radio link, the method comprising the steps of determining a single-input single-output, SISO, radio link operating condition comprising a SISO system gain, and calculating a LOS-MIMO incremental gain of the LOS-MIMO radio link, as well as modifying the determined SISO radio link operating condition by accounting for the calculated LOS-MIMO incremental gain in the SISO system gain to obtain a LOS-MIMO radio link operating condition comprising a LOS-MIMO system gain, and also obtaining a set of operating condition requirements of the LOS-MIMO radio link. The method also comprising the step of predicting the LOS-MIMO radio link performance by comparing the LOS-MIMO radio link operating condition to the operating condition requirements of the LOS-MIMO radio link.
