  • Blind rate detection method and device in asynchronous mobile communication system
    Patent number: 7184409
    Abstract: A blind rate detection method in an asynchronous mobile communication system comprises: restoring data when a path selection (PS) value at a last bit's possible position satisfies a PS condition; determining whether a SER satisfies a SER condition when no error occurs in a CRC; determining whether to update a minimum value of PS values when the SER satisfies the SER condition; setting a PS value of the last bit's possible position as the minimum value of the PS values and the last bit's possible position as a last detection position when updating the minimum value; and repeating the above steps until the last bit's possible position reaches a maximum value, and outputting the last detection position when the last bit's possible position becomes the maximum value.
