  • Patent number: 5440298
    Abstract: In an address receiving mode of a paging receiver, an address codeword contained in each successive batch of a paging signal is compared with the address of the receiver to detect a match. The bit rate of data pulses generated by the receiving section are checked to see if it is in a prescribed range of bit rates. If the receiver fails to detect an address match in one of the batches due to fading, it continuously receives the address codewords in successive batches, rather than returning to standby mode, if the bit rate of the data pulse is determined to be in the prescribed range.
