Abstract:
1. A blind rate detection method in an asynchronous mobile communication system comprising: a) restoring data when a path selection value at a last bit's possible position of a reset last bit satisfies a predetermined path selection condition; b) determining whether a symbol error rate (SER) of the restored data satisfies a predetermined SER condition when no error occurs in a cyclic redundancy code (CRC) of the restored data; c) determining whether it is needed to update a minimum value of path selection values when it is determined that the SER satisfies the predetermined SER condition; d) setting a path selection value of the last bit's possible position as the minimum value of the path selection values and setting the last bit's possible position as a last detection position when it is determined that it is needed to update the minimum value of the path selection values; and e) repeating the steps of a) to d) until the last bit's possible position reaches a predetermined maximum value, and outputting the last detection position when the last bit's possible position becomes the predetermined maximum value.
