摘要： The present invention relates to a method and device for compensation of received signal components at a user equipment (1) (UE) used for receiving signal components from a radio base station (4) (RBS). The signal components have at least a first and a second polarization orientation, respectively. The intended reception of the signal component (8) (y h (n)) having the first polarization deviates from the polarization orientation of the transmitted signal component (6) (X h (n)) having the first polarization by a first angle (φ), and the intended reception of the signal component (9) (y v (n)) having the second polarization deviates from the polarization orientation of the transmitted signal component (7) (x v (n)) having the second polarization by a second angle (β). The method comprises the steps: determining the correlation values (Ry w , Ry vy , Ry yv , Ry yy ) for the received signals (y h , y v ) 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).

摘要： A method (700) for correcting a frequency offset (f e , f' e ) in an OFDM system (100), in which the traffic comprises sub-carriers (fc 1 -fc 12 ). The offset is present in traffic (UL, DL) between a controlling node (110) of a cell (130) in the system and a node such as a user terminal (120) in the cell (130). The correction comprises an interpolation operation (705) of a certain degree being performed on a number (710) of received sub-carriers. The degree of interpolation is determined by using (715) at least one of : the magnitude of the frequency offset, the processor capacity of the node in which the correction is to be performed and the modulation degree in the traffic which has an offset to be corrected, so that the degree of the interpolation can be fitted to the load of the node in which the correction is to be performed.
