Abstract: 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.

Abstract: The present invention relates to a receiver in a 2×2 Line of Sight Multiple Input Multiple Output, LoS MIMO, system. The receiver is arranged to estimate a first (?1) and a second (?2) signal on the basis of a first (r1(t)) and a second (r2(t)) signal received from respective first and second transmitters (Tx1,Tx2). Said received signals (r1(t), r2(t) comprises a first and second signal. The receiver comprises a first Phase Locked Loop (11), PLL, and a second PLL (12), which are arranged to respectively determine a first (In1) and second (In2) demodulated signal from the first (r1(t)) and the second (r2(t)) received signals. The receiver further comprises an equalizer (13) which is arranged to estimate the first (?1) and second (?2) signals from the demodulated signals (In1,In2).
