Abstract: According to an example embodiment, there is provided an apparatus comprising circuitry configured to derive at least two outputs, wherein each output comprises a sum of at least two intermediate signals, the circuitry being configured to derive each intermediate signal by applying a coefficient to a signal received from an antenna element, each output corresponding to an antenna beam, and at least one processing core configured to select from a preconfigured plurality of coefficient sets a first set of coefficients, and to provide the selected first set of coefficients to the circuitry for use in deriving the intermediate signals, the selection being based at least in part on an operating condition relating to the apparatus. The coefficients may be chosen to decrease a correlation between the antenna elements, for example.
