ABSTRACT:
A selective call receiver (10) comprising a processor (108) that couples to a receiver circuit (102), a baud rate detector (106) and a memory device (110). The processor (108) activates the baud rate detector (106) that includes a plurality of registers to perform two baud rate detections to confirm a selective call signal before further processing. When a first baud rate detection detects the selective call signal, the processor (108) combines the results of this first baud rate detection and a plurality of predetermined baud rate parameters to provide a second plurality of predetermined baud rate parameters. The processor (108) then activates the baud rate detector (106) to perform a second baud rate detection using the second plurality of predetermined baud rate parameters. Based on the results of the second baud rate detection, the processor (108) determines whether to continue processing the selective call signal.
