ABSTRACT:
A selective call receiver (200) includes a receiver (204) which receives paging signals, the paging signals have a preamble (102), a synchronization codeword (104), and at least an address information (108, 110). A synchronization obtaining circuit (206), coupled to the receiver (204), obtains synchronization to the paging signal. The synchronization obtaining circuit (206) has a preamble detector (404) which detects preamble (102), a synchronization codeword detector (406), responsive to the preamble being detected, detects the synchronization codeword (104), and address decoder (408), responsive to the synchronization codeword being detected, decodes the address information (108, 110). A synchronization maintaining circuit (224, 408) maintains synchronization to the paging signals during the address decoding, and a baud rate detector (224) detects valid and invalid baud rates during address decoding. An initiating circuit (412), responsive to the invalid baud rate being detected, initiates the synchronization codeword detector (406) for detecting at least one subsequent synchronization codeword.
