    • In a time-division multiplexing wireless communication system, an antenna module has plural antenna elements. Receiver high-frequency circuit synthesizes signals from the antenna elements according to an antenna directivity having a desired beam pattern. Demodulator selects one of the received signals from wireless terminals according to the synthesized received signals, and determines transmission beam direction information for use in directing the beam in the selected direction. Weighting circuit generates weight coefficients for setting of the beam patterns and transmission beam directions according to the transmission beam direction information, and produces transmission time slots according to a table listing the relations of the transmission beam directions and the time slots for use in the beam radiation in those directions. Down-link fixed beam-forming circuit and modulator control the antenna module using the generated beam pattern, beam direction and transmission time slots to transmit the down-link signal.

    • 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.

    • The invention is directed to an ignition coil for an internal combustion engine which includes a columnar member having a plurality of magnetic plates, e.g., silicon steel plates stacked one on the other, each of which is a flat plate with its opposite ends having a width greater than that of its middle portion. Each silicon steel plate has a middle portion whose width is gradually increased from the plates placed at the opposite sides of the columnar member to the plate placed in the center of the columnar member, to form a circular cross section. Whereas, the opposite end portions of the columnar member have a rectangular cross section which is greater in area than the circular cross section of the middle portion, respectively. A plurality of recesses are formed on one side of each steel plate, and a plurality of protrusions are formed on the other side of each steel plate. The silicon steel plates stacked one on the other under pressure, so that the recesses and the protrusions are connected to form a plurality of stacked portions on the columnar member. The ignition coil further includes a primary winding and a secondary winding which are wound around the columnar member, a magnetic cylindrical member in which the columnar member is received, and a magnetic cylindrical case in which the cylindrical member and the columnar member are received.
