Apparatus and method for receiving a forward packet data control channel in a mobile communication system supporting packet data service

摘要

A forward packet data control channel (F-PDCCH) receiver for reducing alarms relating to errors in a packet data control channel for transmitting a control signal in a mobile communication system and a method of using the same. In the F-PDCCH receiver, a decoding part decodes received symbols and calculates an information word and an absolute value of a difference between two path metrics. A false alarm reduction function compares the absolute value received from the decoding part with a predetermined threshold, and outputs a decoding value indicating whether an alarm is generated according to the comparison result. A blind slot format detector detects a blind slot format based on the absolute value received from the decoding part.
