Abstract
A method and device for compensation of received signal components at a user equipment (UE) used for receiving signal components from a radio base station (RBS). The signal components have at least a first and a second polarization orientation, respectively. The intended reception of the signal component (Y(n)) having the first polarization deviates from the polarization orientation of the transmitted signal component (X(n)) having the first polarization by a first angle (φ), and the intended reception of the signal component (Y(n)) having the second polarization deviates from the polarization orientation of the transmitted signal component (xv(n)) having the second polarization by a second angle (θ). The method comprises the steps: determining the correlation values (Ry, Ry, Ry, Ry) for the received signals (Y, Y) at a first time (k) and a second time (m); using these values to determine the deviation angles (φ, θ) performing said compensation using the deviation angles (φ, θ).
