The described paging system is capable of effectively transmitting and receiving message codes without adversely affecting the paging code (especially address code) reception probability. …<??>The paging receiver comprises a receiver device (1, 2, 3) for receiving a paging code including a first code having a first transmission rate, a second code having a second transmission rate and a discrimination code for distinguishing the first and second codes. A low-pass filter LPF (4) is connected to the output of the receiver device (1, 2, 3) for switching its cut-off frequency in response to a control signal (S2) and selectively extracting the first and second codes. A data processing section (12) is coupled to the output of the LPF (4) for generating the control signal (S2) in response to the received discrimination code, supplying the control signal (S2) to the LPF (4), and decoding the extracted first and second codes. |
