摘要：An apparatus and method for detecting a pilot signal in a mobile

communication system are provided by which the processing time taken to demodulate atraffic channel based on a channel estimation result can be reduced, and thus, the size of

a buffer for buffering signals until the presence of a secondary/auxiliary pilot signal isdetected can also be reduced. The apparatus includes a first channel estimator forestimating a channel for a noise component of a pilot symbol received by a first receiver,a second channel estimator for adding a pilot symbol received by a second receiver andthe pilot symbol received by the first receiver and estimating a channel for a noisecomponent of the added pilot symbol, an energy detector for detecting an energy valueof a pilot symbol using result values output from the first and second channelestimators, and a comparison and determination unit for determining whether or notthere is a secondary/auxiliary pilot signal by using the detected energy values.
