    • A receiving device in a multi-carrier CDMA communication system. In the receiving device, a time compensation means has a time tracker for each of signals received on multi-carriers and generates a time delay compensation signal by combining time errors of the carriers received from the time trackers. A first PN sequence generator generates a first PN sequence whose time delay is compensated for by the time delay compensation signal. A plurality of PN despreaders PN-despread the signals received on the multi-carriers by the first PN sequence. A frequency compensation means detects pilot signals corresponding to the PN-despread signals, generates frequency error signals for the carriers by the detected pilot signals, and compensates for frequency errors of the signals received on the multi-carriers. A phase compensation means compensates for phases for the carriers using the PN-despread signals and the pilot signals. A multiplexer multiplexes the phase-compensated signals.
    • 一种多载波CDMA通信系统中的接收装置。 在接收装置中,时间补偿装置具有用于在多载波上接收的每个信号的时间跟踪器,并且通过组合从时间跟踪器接收的载波的时间误差来产生时间延迟补偿信号。 第一PN序列发生器产生其时间延迟由时间延迟补偿信号补偿的第一PN序列。 多个PN去扩频器通过第一PN序列PN扩展在多载波上接收的信号。 频率补偿装置检测对应于PN解扩信号的导频信号,通过检测到的导频信号产生载波的频率误差信号,并补偿在多载波上接收的信号的频率误差。 相位补偿装置使用PN解扩信号和导频信号来补偿载波的相位。 复用器复用相位补偿信号。

    • An apparatus and method for receiving control information transmitted from a transmitter using one of a plurality of slot lengths in a high-speed packet transmission mobile communication system is provided. The apparatus and method includes a decoder adapted to receive symbols by the slot, and generate at least one bit stream by decoding as many symbols of at least one possible slot length among a plurality of slot lengths according to a previous decoding result. An error checker adapted to perform error checking on the bit stream from the decoder. A controller is adapted to provide symbols of one more consecutive slot to the decoder, if the error checking failed, and acquire control information from the error checking-passed bit stream, if the error check passed. The decoder is further adapted to output at least one frame quality metric for the bit stream along with the bit stream. If the number of error checking-passed bit streams is larger than or equal to 2, the controller compares frame quality metrics for the bit streams and selects one bit stream having the maximum frame quality metric in order to acquire the control information.

    • A Hybrid Automatic Repeat reQuest (HARQ) control apparatus and method for detecting a message received over a packet data control channel in a mobile communication system are provided in which a base station transmits a packet data control message over at least one packet data control channel and transmits packet data to a mobile station over a packet data channel. A control channel decoder decodes a control message received over the packet data control channel. Based on the decoded control message, the HARQ controller determines at least one of whether to perform demodulation and decoding on a packet received over the packet data channel, whether to update a Walsh mask, and whether to perform state transition on the mobile station. The HARQ controller based on the determination performs at least one of the following functions: outputs demodulation and decoding parameters, updates a Walsh mask, and outputs a state transition value to an upper layer. A data channel demodulator demodulates packet data received over the packet data channel upon receiving a demodulation parameter from the HARQ controller. A decoder decodes the packet data demodulated by the data channel demodulator upon receiving a decoding parameter from the HARQ controller.
