Abstract: There is provided an apparatus and method for using QOF (Quasi-Orthogonal Function) Walsh codes when enough orthogonal Walsh codes are not available for a packet data service in a mobile communication system supporting concurrent provision of a high rate packet data service and a circuit call service. A data rate (DR1) in the case of using available orthogonal Walsh codes is first obtained. Then, a data rate (DR2) in the case of using QOF Walsh codes is obtained considering a power reduction factor due to the increase of interference involved with the use of the QOF Walsh codes. Packet data is transmitted at a higher data rate of DR1 and DR2. At the same time, information about the selected data rate and information about whether the QOF Walsh codes are used or not are transmitted.

Abstract: Provided is an apparatus and method for canceling an interference signal in a packet data receiver in which data is transmitted and received over a packet data channel and a packet data control channel. The packet data channel is time-synchronized with the packet data control channel. A buffer temporarily stores a signal on the packet data channel, combined after being received through multiple paths, until the packet data control channel is decoded. An interference cancellation controller analyzes packet data control channel information obtained by decoding the packet data control channel, and outputs an interference cancellation command signal only when it is determined that effective packet data to be received exists in a current time slot. An interference cancellation section receives the packet data channel signal output from the buffer, and cancels an interference signal from the packet data channel signal only when the interference cancellation command signal is received.

Abstract: An apparatus and method for compensating the gain of an Automatic Gain Controller (AGC) for stabilizing the reception power of discontinuously transmitted packet data in a mobile communication system are disclosed. A compensation controller receives an AGC value from the AGC, sampling the AGC value by a predetermined sample number for a predetermined period, and obtains an AGC compensation gain by comparing a predetermined value with the difference between a sampled AGC value with a reference gain for the predetermined period. A compensator compensates the AGC value with the AGC compensation gain, thereby correcting errors generated in view of the nature of the AGC.

Abstract: An apparatus for detecting a frame transmission period in a CDMA mobile communication system supporting a discontinuous transmission mode. A first frame detector performs primary frame detection by calculating a signal-to-interference ratio (SIR) using traffic symbol energy, pilot symbol energy and noise energy measured for a predetermined time period, and comparing the SIR with a predetermined frame detection threshold value. A decoder calculates a symbol error rate (SER) by decoding symbols received for the predetermined time period. A second frame detector selects an SER threshold value according to frame detection information from the first frame detector, and compares the selected SER threshold value with the SER to determine whether a frame has been transmitted.
