A selective call receiver (200) includes a receiver (204) receiving paging signals including a preamble, a synchronization codeword, and at least address information. A controller (206) controlling a supply of power to the receiver for receiving the paging signals. A synchronization obtaining circuitry (404, 406, 224), coupled to the receiver (204), obtains synchronization to the paging signal. The synchronization obtaining circuitry (404, 406, 224) includes a baud rate detector and synchronization codeword detector, coupled to the baud rate detector, detects the synchronization codeword. An address decoder, responsive to the synchronization codeword being detected, decodes the address information. A synchronization maintaining circuitry (404, 408, 224) maintains synchronization to the paging signals during address decoding. The synchronization maintaining circuitry (404, 408, 224) includes circuitry for enabling the power switch (210) which enables the receiver (204) for receiving the paging signals. The baud rate detector (224), responsive to the power being supplied to the receiver (204), detects baud rate during at least first (150) and second (152) portions of the address. A preamble detector (404), responsive to the second portion of the address being received, detects preamble during at least a portion of a second address (152). |

DETAILED DESCRIPTION A selective call receiver comprises means for receiving paging signals including a preamble, a synchronization codeword, and at least an address information.
Means for controlling a supply of power to said receiving means for receiving the paging signals.
Means, coupled to the receiving means, obtains synchronization to the paging signal.
The synchronization obtaining means comprises means for detecting baud rate; and means, coupled to the baud rate detecting means, for detecting the synchronization codeword.
Means, responsive to the synchronization codeword being detected, decodes the address information.
Means for maintaining synchronization to the paging signals during the address decoding.
The synchronization maintaining means comprises means for selectively enabling the power supply controlling means for receiving the paging signals.
The baud rate detecting means, responsive to the power being supplied to the receiving means, detects baud rate during at least first and second portions of the address.
Means, responsive to the second portion of the address being received, for detecting preamble during at least a portion of a second address.
A method for reducing power consumption in a selective call receiver which consumes power, the method comprising the steps of: (a) receiving paging signals including a preamble, a synchronization codeword, and at least an address information; (b) controlling a supply of power to said receiving means for receiving the paging signals; (c) obtaining synchronization to the paging signal wherein the steps of obtaining synchronization comprising the steps of: (d) detecting baud rate; and (e) detecting the synchronization codeword; (f) decoding the address information in response to step (c); (g) maintaining synchronization to the paging signals during the address decoding, said step of maintaining synchronization, comprising the steps of: (h) selectively enabling the power supply controlling means for receiving the paging signals; (i) detecting baud rate during at least first and second portions of the address; and (j) detecting preamble during at least a portion of a second address
