发明名称 PAGING RECEIVER HAVING BATTERY SAVING CIRCUIT
摘要 The invention relates to a paging receiver comprising a rereceiving section for receiving a paging signal which includes a preamble signal, a sychronization codeword and an address codeword, switch means (16) for controlling power supply to said receiving section in response to a control signal, means (32) for detecting the preamble signal to produce a preamble detect pulse (PD), means (33) for detecting said synchronization codeword to produce a synchronization codeword detect pulse (SCD), means (34) for detecting said address codeword to produce an address codeword detect pulse (IDD), error detector means (35) for detecting an error in said address codeword and producing an error detect pulse (NBD) when the number of errors detected is greater than a predetermined value, and a controller (36) for generating said control signal and applying said generated control signal to said switch means. The paging receiver is operable with an improved battery saving efficiency during reception of the paging signal.
