  • Method and apparatus for batery saving in a communication receiver
    Patent number: 5542117
    Abstract: A method and apparatus in a receiver (110) for use in a selective call communication system (100) conserves battery power. The system (100) utilizes a signaling protocol (300) comprising a first bit and frame sync (320) transmitted at a predetermined baud rate, followed by a second bit and frame sync (322) transmitted at a second baud rate. The first bit and frame sync (320) defines the second baud rate. The receiver (110) synchronizes (406, 410) with the first bit and frame sync (320), determines (416) therefrom the second baud rate, and battery saves (420) during transmission of the second bit and frame sync (322) in response to determining that the second baud rate is equal to the predetermined baud rate.
