Receiving circuit, method for receiving a signal, and use of a detection circuit and a control circuit

A receiving circuit of a node of a radio network, the receiving circuit comprising:

• an input circuit that is connectable to an antenna to receive a signal;
• 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 is formed 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.
