    摘要： If a code is transmitted at a first transmission rate, a base station modulates the entirety of the code, namely a preamble, a synchronizing signal and a call-data, by two values and transmits them at the first transmission rate. If the code is transmitted at a second transmission rate, which is double the first transmission rate, the base station modulates the preamble and the logically inverted synchronizing signal (obtained by inverting the "1", "0" logic of the original synchronizing signal) by the two values, transmits them at the first transmission rate, modulates the call-data by four values and transmits it at the second transmission rate. As a result, it suffices to provide the pager with a single common preamble detector and a single common synchronizing detector, irrespective of the transmission rate. Moreover, by detecting the synchronizing signal or its inverted version, it is possible to determine whether the call-data has been modulated by two values or four values, thereby assuring that the call-data following the synchronizing signal can be modulated correctly.

    摘要： A mobile radio system has an upward and downward control channel for controlling a call-out transmitted from a mobile terminal station, independently from a communication channel. The system detects an abnormal state of an automobile equipped in the mobile terminal station, and automatically transmits a call-out signal through the upward control channel to said base station when the abnormal state is detected. The abnormal state occurs when a door is opened, for example. It receives a response signal via the downward control channel from a base station, the response signal corresponding to the call-out signal of the terminal station, and produces an alarm sound when identification signal ID of the terminal station is detected from the response signal. Thus, the abnormal state of the automobile can be indicated by the alarm sound outputted from the portable receiver, thereby preventing the automobile from theft.
