摘要： A speech signal is analyzed for each frame so that it is separated into spectral envelope information and excitation information, and the excitation information is expressed by a plurality of pulses. Judgement is conducted as to whether the current frame is a voiced frame immediately after the transition from an unvoiced frame, a voiced frame continuative from a voiced frame or an unvoiced frame, and excitation pulses are generated in accordance with the judgement result. In case of a continuing voiced frame, the excitation pulse position of the current voiced frame is determined based on the pitch period with respect to the excitation pulse position of the immediately preceding voiced frame so that the excitation pulse train is generated at a position approximated to the determined position.

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： In a mobile communication system, the tracking of synchronization is conducted in a stable state even in a multipath environment. A delay profile detector calculates a delay profile a(n) using a despread signal for each processing unit n. A delay profile averaging unit averages a(n) to produce Ave(|a(n)|2). A data symbol detector conducts rake combining of the despread signal using a(n) and Ave(|a(n)|2). According to a(n) and Ave(|a(n)|2, a weighting function unit calculates a representative value representing delay waves. A loop filter generates a control signal in response to the representative value. A clock controller controls a spread code generator according to the control signal.

摘要： 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.
