摘要： A base station creates a dummy pattern added with an error correction code, during occurring of a control channel not allocated for transmission of control information, transmits the dummy pattern instead of control information at a power level lower than a normal power level. A mobile station decodes control information transmitted through the control channel, examines whether or not a value specified by the decoded control information is within a suitable range, and performs error detection of the decoded control information. The mobile station stops decoding of data transmitted through a data channel, upon judging that the value is not within the suitable range or detecting an error in the error detection.

摘要： A coherent bandwidth calculation unit (41) calculates a coherent bandwidth based on a channel response in the time domain obtained from reception signals (R1-RN) for each path between transmitting antennas and receiving antennas. A weight calculation control unit (42) determines target subcarriers of equalization weight calculation based on the coherent bandwidth. A weight calculation unit (31) calculates the equalization weight of each target subcarrier. A weight interpolation unit (43) performs interpolation processing using the equalization weights so as to obtain equalization weights for the subcarriers that have not undergone equalization weight calculation yet.

摘要： Parallel interference cancellers are connected in successive stages. In each canceller, multiple signal paths are provided for interference replica estimators to receive multiple CDMA channels. A spread code is generated for each signal path for dispreading the path components of the channel. In each signal path, the despread components are RAKE combined and a symbol replica is detected therefrom either by detecting or estimating the type of modulation. The detected symbol replicas are re-modulated and then re-spread to produce interference replicas. In each stage, the interference replicas are summed and subtracted from a delayed CDMA signal and then summed with the interference replicas of the same stage. Output signals from the final stage are despread and symbol replicas are recovered therefrom. For each signal path, a spread code is detected from a control channel and compared to the generated spread code. Those symbol replicas where a coincidence is detected are supplied to respective decoders and diversity combined.
摘要翻译：并行干扰消除器连续连接。在每个消除器中，为干扰副本估计器提供多个信号路径以接收多个CDMA信道。为每个信号路径生成一个扩展码，用于分散通道的路径分量。在每个信号路径中，解扩组件是RAKE组合的，并且通过检测或估计调制类型来检测符号副本。检测到的符号副本被重新调制，然后重新扩展以产生干扰副本。在每个阶段，将干扰副本从延迟的CDMA信号中相加和相减，然后与同一级的干扰副本相加。来自最终级的输出信号被解扩并且从其中恢复符号复制品。对于每个信号路径，从控制信道检测扩展码并与所生成的扩展码进行比较。将检测到符合的符号复制品提供给相应的解码器并进行分集组合。
