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.

Abstract: A method for battery saving in a selective call receiver (20) that comprises a baud rate detector (210) and a receiver circuit (202) for receiving and demodulating a selective call signal. The selective call signal comprises a preamble (102) and a plurality of data batches. Each of the plurality of data batches further comprises a synchronization codeword (104) and a plurality of assigned data frames (106). The method (30) begins when a predetermined baud rate is detected in each of the plurality of assigned data frames (106) in one of the plurality of data batches. Upon detecting the predetermined baud rate, the selective call receiver (20) inactivates the receiver circuit (202) for the duration of the synchronization codeword (104) in a subsequent one of the plurality of data batches. Otherwise, the receiver circuit (202) remains activated during the synchronization codeword (104) of the subsequent one of the plurality of data batches.
