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.

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 transmitting and receiving a symbol through a reverse control channel in a mobile communication system for providing packet data are provided. When reverse traffic is present, the apparatus and method can effectively demodulate and decode the reverse traffic. In a method for transmitting a reverse channel in the mobile communication system capable of discontinuously transmitting packet data, a transmission is performed by setting power of a Data Rate Indicator (DRI) channel to a predefined power when packet data is transmitted. When no packet data is transmitted, a transmission is performed by decreasing the power of the DRI channel.

摘要： An apparatus and method for receiving data in a mobile station for a mobile communication system using multi-user packet data are provided, in which a preamble power measurer measures preamble power of the multi-user packet data received from a base station and transmits the result value to a controller. The controller compares the measured power with a predetermined threshold, simultaneously decodes the multi-user packet data according to all transport formats if the measured power is lower than the threshold, and decodes the multi-user packet data according to a predetermined transport format if the measured power is higher than or equal to the threshold. A plurality of decoders decode the received multi-user packet data according to a control signal from the controller, wherein the number of the decoders depends upon the total number of transport formats for the multi-user packet data.

摘要： A TDM (Time Division Multiplexing)-based mobile communication system that switches a service type according to QoS (Quality of Service). The mobile communication system includes a base transceiver system (BTS) and a mobile station (MS) connected to the BTS. The BTS monitors whether a first service provided from the BTS to the MS is satisfied according to whether at least as much data as a predetermined transmission amount is transmitted to the MS. If the first service is dissatisfied, the BTS switches a service to a second service lower in QoS than the first service so that as much data as a transmission amount smaller than the predetermined transmission amount is transmitted to the MS.
