Patent ID: 7965993

Claim:
Method for compensation of received signal components at a user equipment (UE) used for receiving signal components from a radio base station (RBS), which signal components have at least a first and a second polarization orientation, respectively, which signal components have been transmitted in a channel, and where the intended reception of the signal component (Y h (n)) having a first polarization deviates from a polarization orientation of the transmitted signal component (x h (n)) having the first polarization by a first angle (φ), and where the intended reception of the signal component (y v (n)) having a second polarization deviates from the polarization orientation of the transmitted signal component (x v (n)) having the second polarization by a second angle (β), wherein the method comprises the steps: determining correlation values (Ry vv , Ry vy , Ry yv , Ry yy ) for the received signals (Y h , Y v ) of the at least two different polarization orientations at a first time (k) and a second time (m); using the determined correlation values (Ry vv , Ry vy , Ry yv , Ry yy ), to determine deviation angles (φ, θ) between the polarization orientations of the transmitted (x h (n), x v (n)) and the received (y h (n), y v (n)) signal components; performing said compensation of the received signal components (y h (n), y v (n)) using the deviation angles (φ, θ).
