    摘要: A non-orthogonal noise detecting device for a CDMA communication system. In the device, a despreader despreads multiple channel signals including a specific channel with an orthogonal code assigned to the specific channel repeating at least two same second symbols at a given first symbol duration, to generate despread repeated symbols. A difference signal generator receives the despread second symbols, and generates a difference signal between a presently received second symbol and a previously received second symbol. A noise detector converts the difference signal to an energy value to generate a non-orthogonal noise signal.

    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 rake reception apparatus for determining whether a paging channel is received in a mobile terminal using a Discontinuous Reception (DRX) mode. A searcher searches for a multi-path signal using a received signal output from a Radio Frequency (RF) part, and calculates an energy value for each hypothesis. A demodulator demodulates a Paging Indicator (PI) for a hypothesis for which an energy value calculated by the searcher exceeds a valid path threshold. A controller determines whether a paging channel is received, according to the demodulated signal output from the demodulator, and performs finger allocation using a multi-path search of the searcher if it is determined that the paging channel is transmitted.

    摘要: A CDMA communication system transmits packet data via a designated forward channel which uses a particular spreading code, in the case where a base station has the packet data to send to a mobile station while the mobile sation does not have a dedicated channel established. A base station includes a first channel transmitter for transmitting a control message including information representative of a spreading code for designating a specific forward common channel to a specific mobile station, to the mobile station via a forward common channel, and a second channel transmitter for spreading user data with the spreading code upon reception of a response to the control message and transmitting the spread user data. A mobile station includes a control message analyzer for analyzing a message including information representative of a designated spreading code received via a forward common channel, and a forward common channel receiver for despreading user data spread with the designated spreading code generated based on the information, using the spreading code.
