摘要： A low-cost communication system utilizing a code division multiple access, which controls scale-up of an apparatus due to the provision of an interference suppressing function in a base transceiver station, prevents the reduction of channel utilization efficiency, and enables a high-quality communication. Conventionally, a signal obtained through an interference cancellation stage process has been processed at subsequent cascade-connected stages. The interference cancellation stage process has been carried out by cascade-connecting several circuits performing the same process in a multi-stage interference-canceling device. However, in the present invention, by performing a demodulation process for generating replica signals, feeding back the replica signals to a correlation circuit for another demodulation process, and repeating the same signal process, the interference cancellation stage process is carried out. Such a configuration enables reduction of hardware.

摘要： 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 demodulator 302 which executes the demodulation processing of a common control channel as to a received baseband reception signal 301, an interference canceller 309 which 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 processor 315 which 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 demodulator 302 and is not submitted to interference cancellation processing, thereby to heighten the processing speed of system information. In the interference canceller 309, 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.

摘要： The present invention is a process for producing a rigid foam by reacting an active hydrogen compound containing an active hydrogen compound containing in its molecular structure a group of a neutralized salt or an alkoxide and a polyisocyanate compound in the presence of a halogenated hydrocarbon blowing agent and an assisting agent such as a catalyst.The active hydrogen compound containing in its molecular structure a group of a neutralized salt or an alkoxide and other active hydrogen compounds are preferably polyols, particularly polyether polyols respectively.The present invention has solved a problem of deterioration of the physical properties, which is problematic in a case where a rigid foam is produced by using a halogenated hydrocarbon blowing agent having hydrogen atoms, and is capable of producing a rigid foam equivalent to a conventional rigid foam obtained by using a halogenated hydrocarbon blowing agent having no hydrogen atoms.
