Patent ID: 8363708

Claim:
A receiving circuit of a node of a radio network, the receiving circuit comprising: an input circuit that is operable to receive a signal from an antenna; an evaluation circuit that is connected downstream of the input circuit in the receive path, and wherein the input circuit is configured for analog signal processing with an analog-to-digital conversion of the received signal into a digital signal, and wherein the evaluation circuit is configured to evaluate the digital signal and has a detection circuit, a check circuit, and a control circuit, the detection circuit being configured to determine digital data from the digital signal, the check circuit being configured to save the digital data and to check a current frame of the digital data and to output at least one test signal based on the checking, and the control circuit being connected to the check circuit and a control input of the detection circuit and configured to activate or deactivate the analog signal processing and/or the determination of the digital data by a control signal at the control input of the detection circuit and/or at a control input of the input circuit depending on the at least one test signal; wherein the check circuit is configured to compare an address contained in a frame of the digital data with an identification of the node and is configured to output a first test signal corresponding to a comparison result of the comparison; and wherein the control circuit is configured to output the control signal to deactivate the determination of the digital data if the first test signal indicates that the address matches the identification of the node.
