Abstract: In a method for searching for signals among interference signals in a multi-channel radio receiver, at least two different data signals are transmitted on at least one physical channel of a radio system to a common receiver. The search for a signal is initiated on any channel, starting with a sequential search of a useful signal by measuring the current signal strength in the form of the RSSI value; a search is made for a signal criterion of the signal and when said criterion has been identified, the measured RSSI value is compared with a predefined RSSI threshold value; if the RSSI threshold value is exceeded, the search for a signal is switched to a search for a data frame and if a data frame is found, the useful data is read; if no signal criterion is identified, if the RSSI threshold value is not exceeded and if no data frame is found, the procedure is interrupted and a new search operation is initiated once a new RSSI threshold value has been defined.

Abstract: The invention relates to a method and apparatus for protecting a transmission path between a base unit and a mobile key unit in an access control system, in particular for motor vehicles. A carrier signal which is modulated with a user signal is transmitted from a transmitting unit to a receiving unit. According to the invention, a separate reference signal, which has a fixed phase angle with respect to the carrier signal, is also transmitted. The phases of the reference signal and of the carrier signal are compared in a test circuit, and an alarm signal is emitted if a phase difference which varies with time is found.

Abstract: Remote access (for example to a motor vehicle) is controlled with a configuration having a transceiver unit. The transceiver unit outputs an interrogation signal which activates all available access code transmitters at the same time, and all the access code transmitters which receive this interrogation signal then transmit their specific access code signals, essentially at the same time. The transceiver unit separates the access code signals received at the same time on the basis of a characteristic applied to them.
