Abstract
In a mobile communication system employing code division multiple accesses and having radio logical channels such as control channels and traffic channels, for the purpose of interference cancellation processing which is implemented without a large processing delay even under a call control application, the baseband receiving part of the mobile communication system includes a common control channel demodulatorwhich executes the demodulation processing of a common control channel as to a received baseband reception signal, an interference cancellerwhich executes interference cancellation processing for a received multiplexed signal on the basis of the notification information of the control channels, and a synthesis/error correction processorwhich executes error correction processing, etc. as to user information having undergone the interference cancellation processing and thereafter executes frame formation processing. The common control channel is demodulated by the common control channel demodulatorand is not submitted to interference cancellation processing, thereby to heighten the processing speed of system information. In the interference canceller, cross-correlation interferences are cancelled as to the dedicated control channel and the traffic channel other than the common control channel, thereby to enhance a channel efficiency.
