    摘要: A method and apparatus provide a broadcast parameter message in a mobile communication system providing a broadcast service. If the provided broadcast service is time domain multiplex (TDM)-multiplexed, a message generator generates the broadcast parameter message by setting a field indicating the TDM multiplexing, setting a field indicating a position of the broadcast service in each sub-buffer, setting a field indicating whether one sub-buffer includes one service and a field indicating validity of the field, and setting a field exclusively indicating actual broadcast service data stored in one sub-buffer. A transmitter modulates the broadcast parameter message and provides the modulated broadcast parameter message to a terminal that receives the broadcast service.

    摘要: A method and apparatus for performing Reed-Solomon (R-S) coding in a mobile communication system supporting a broadcast and multicast (BCMC) service are provided, where a determination is made as to whether a change in a broadcast overhead message (BOM) exist including information with parameters used for the BCMC service. A position of data in a new channel encoder buffer is calculated at a time when the BOM is changed. The channel encoder buffer is filled with predetermined data in an interval ranging from a start point of a buffer comprising data in the change point of the BOM to a point preceding a point of data first transmitted according to the changed BOM.

    摘要: Disclosed is an apparatus and method for receiving a signal transmitted through a multi-path in a wireless communication system, and more particularly an apparatus and method for removing a fake path detected by the ripple of a baseband pulse shaping filter to detect the position of an effective multi-path signal in a direct sequence Code Division Multiple Access system. The method for detecting a fake path in a user equipment in a mobile communication system includes detecting peak indexes and peak energies of peaks of signals received from node B, performing a fake path check with respect to the peaks based on the peak indexes and peak energies, and allocating fingers to peaks which have been determined not to be caused by a fake path as a result of the fake path check.

    摘要: An apparatus and a method for estimating a channel in a Broadband Wireless Access (BWA) communication system are provided. The apparatus includes a subcarrier demapper for extracting pilot symbols at preset positions for a channel estimation; and a channel estimator for acquiring channel estimate values of subcarriers through an Infinite Impulse Response (IIR) filtering using the pilot symbols provided from the subcarrier demapper and a preset filter factor. Thus, the channel condition can be estimated by taking into account the channel change.
