Abstract

The invention relates to a method for lobe shifting in a telecommunication system and an arrangement in a lobe forming network, wherein a fine tuning device is arranged to achieve interpolation between fixed lobes (LF1-LFn) to create an interpolated lobe with an arbitrary direction between the fixed lobes. The fine tuning device according to the invention supports interference cancellation.
