Abstract: The present invention is related to a circuit for encoding at least two input symbols by means of a space-time block code, comprising a plurality of multiplexers, each arranged to receive the input symbols and to output a selected symbol, storing means for storing information on which input symbol is to be selected in each multiplexer of the plurality of multiplexers and for storing gain factor information to multiply the multiplexer outputs with, calculation means, coupled with the storing means, for determining an encoded version of the input symbols based on the multiplexer outputs and corresponding gain factors stored in the storing means. The invention further discloses a corresponding circuit for space-time block decoding.

Abstract: The present invention is related to a method for operating a mobile device comprising a navigation receiver and a communication terminal. The method comprises the steps of obtaining by means of the navigation receiver information indicative of the reception conditions, deriving from the information indicative of the reception conditions assistance data information for controlling operation of the communication terminal, operating the communication terminal exploiting the assistance data information.
