Abstract: A method of processing a plurality of received digitized signals may include determining a plurality of cross-correlation coefficients for the plurality of received digitized signals; forming a cross-correlation coefficient vector including the plurality of cross-correlation coefficients; and determining an evaluation value for at least some of the plurality of cross-correlation coefficients. The determining the evaluation value may include: pre-selecting a predefined number of cross-correlation coefficients from the cross-correlation coefficient vector and deleting the pre-selected number of cross-correlation coefficients from the cross-correlation coefficient vector; after the pre-selection, determining an averaging value using at least one of the non-preselected cross-correlation coefficients of the cross-correlation coefficient vector; and determining the evaluation values based on the respective value of the pre-selected cross-correlation coefficient and the averaging value. The method may further include selecting one or more cross-correlation coefficients based on the determined evaluation values; and further processing based on the selected one or more cross-correlation coefficients.

Abstract: A circuit may include at least one amplifier circuit configured to amplify a received signal having a first signal received in a first time interval and a second signal received in a second time interval. The first signal and the second signal are signals sent by a different number of coherent wireless signal sources. The circuit arrangement may further include at least one gain control circuit connected to the at least one amplifier circuit and configured to determine a first expected received signal strength of the first signal, to determine a second expected received signal strength of the second signal, and to determine a gain level based on the first and second expected received signal strengths. The at least one amplifier circuit may be configured to amplify the first signal using the determined gain level and to amplify the second signal using the determined gain level.
