摘要： An apparatus and a method for detecting traffic channel signal transmission in a rake receiver may advantageously ensure stable and accurate detection performance in performing continuous/discontinuous transmission detection of traffic channels with a rake receiver in a mobile communication system based upon CDMA 2000 standards by making sufficiently spaced distribution in traffic channel signal-to-noise ratios estimated in continuous/discontinuous transmission. The method includes compensating traffic channel signals according to fingers, respectively, by using estimated pilot channel signals; combining the compensated finger-based traffic channel signals and estimating signal-to-noise ratios for traffic channels; and comparing the estimated signal-to-noise ratios with a preset threshold value, respectively, to detect continuous or discontinuous transmission of the traffic channels based upon comparison results.

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 a traffic 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 is detected can also be reduced. The apparatus includes a first channel estimator for estimating 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 and the pilot symbol received by the first receiver and estimating a channel for a noise component of the added pilot symbol, an energy detector for detecting an energy value of a pilot symbol using result values output from the first and second channel estimators, and a comparison and determination unit for determining whether or not there is a secondary/auxiliary pilot signal by using the detected energy values.
