Abstract: A method for receiving a normal or an inverted paging signal in a radio pager, which includes the steps of detecting a preamble of a paging signal by reading a cap-code identifying an inherent address of the radio pager and synchronizing with a reference channel frequency; deciding a form of assumption of the paging signal to be received by confirming whether a local area is serviceable according to the detection of a sync code after a predetermined time period; and receiving the paging signal by inverting the same when the local area is not serviceable, and receiving the paging signal as is when the local area is serviceable.
