Abstract:
1. A packet data control channel receiver in a mobile communication system having a packet data control channel capable of transmitting packet data and transmitting control information related to transmission of the packet data, comprising: a packet data control channel decoding part for decoding symbols received over the packet data control channel and outputting a decoded information word and at least one decoding probability value of the information word; a false alarm reduction function for comparing the at least one decoding probability value of the information word with a corresponding predetermined threshold, and outputting a decoding validity value according to the comparison result; a switch for switching an output of the information word according to the decoding validity value; a blind slot format detector for detecting a particular slot format when the packet data control channel has multiple slot lengths; and a Cyclic Redundancy Check (CRC) checking part for performing CRC check on the information word output from the packet data control channel decoding part, and outputting the CRC check result to the blind slot format detector.
