Patent ID: 7702051

Claim:
A reception system for motor vehicles, comprising: a multi-antenna system having at least two antennas for producing reception signals, at least one receiver circuit, at least one individually adjustable phase rotation element, with at least one phase rotation element for receiving reception signals from a corresponding antenna; a plurality of individually adjustable switching elements for switching through or interrupting a signal flow, wherein each of said switching elements respectively, is present in a reception path of each antenna, and wherein said reception signals are guided by way of said at least one individually adjustable phase rotation element; a linear summation circuit wherein said plurality of adjustable switching elements pass said reception signals to said linear summation circuit to form a summarized signal; a level indicator for indicating the level of the summarized signal in the form of a level signal and in communication with said at least one receiver circuit; and a computer device having a memory and having an input coupled to an output of said level indicator, said computer device for receiving said level signal, and having an algorithm stored on said memory of said computer device wherein said algorithm performs calculations for determining a set of phase differences of the reception signals that are present at an input of said summation circuit ( 5 ) at a given setting of said phase rotation elements from their level conditions, so that a determination of said phase differences, by means of calculations, is given on a basis of level measurement samples of said measurement level signal that are performed one after the other, in terms of time, and obtained by way of switch setting signals and phase setting signals brought about by said computer device in the case of differently defined settings of said switching elements or of said phase rotation elements, respectively, and wherein said phase setting signals are generated on the basis of the phase differences determined by calculations, for the subsequent setting of the phase rotation elements for phase alignment of the reception signals that are present at the input of the summation circuit when said plurality of adjustable switching elements are switched through and wherein said output of said summation circuit is in the form of a phase aligned summed signal that is passed to said receiver circuit.
