Abstract: On the side of a mobile station, interference of a perch channel with call control information or a traffic channel is reduced, realizing stable communication. In a method of CDMA communication in which communication is made through the traffic channel for transmitting user data and the perch channel for transmitting a spreading code used for demodulation of the user data, the traffic channel has a call control channel subjected to the time division multiplex, and that call control channel and a part of the perch channel, which is non-orthogonal to the call control channel, are arranged not to overlap with each other in a time base.

Abstract: In the conventional peak factor reduction technique, since the signal has been changed over broad time width before and behind the peak amplitude, the deterioration in signal quality has been great. Through the use of a compensating signal having impulse property that is generated on the peak amplitude, subtraction from the peak amplitude will be performed. Thereby, since it is possible to reduce the deterioration in signal quality that occurs when reducing the peak factor, the peak factor reduction effect can be further enhanced in the same deterioration in signal quality as the conventional one.

Abstract: The present invention reduces the number of base stations required to carry out terminal position detection. A base station which serves for terminal position detection using radio signals comprises an antenna to transmit and receive a radio signal; a radio signal receiver which generates a received signal from the radio signal received; a signal processing unit which processes the received signal and generates a transmit signal; a radio signal transmitter which generates a radio signal from the transmit signal; a control unit which exerts control of the base station operation; and a signal processing unit for position detection which performs signal processing for terminal position detection. A signal receivable range with which a signal can be received by the radio signal receiver is made longer than a signal transmission range with which a signal is transmitted by the radio signal transmitter.

Abstract: When a strobe flash is not emitting light, a photoreception current that is output from a phototransistor is detected and correction current corresponding to amount of extraneous light is produced by a voltage-controlled current source. Further, a light-emission control apparatus, receives emitted light reflected from the subject and halts the light emission when a value obtained by integrating a photoreception signal exceeds a first predetermined threshold value. If a period of time from start of light emission by the discharge tube to that at which the integrated value exceeds the threshold value falls within a predetermined period of time, the integrated value is reset and integration is performed again. Further, the aperture of a diaphragm is reduced and the threshold value is raised from the first threshold value to a second threshold value.

Abstract: A code division multiple access (CDMA) mobile communication system with improvements to permit stable reception with a minimum of bit error. The system comprises a voltage-controlled oscillator for supplying a carrier to a radio frequency quadrature demodulator, and a frequency controller for detecting a frequency error from a phase correction signal of the first step to generate a control signal that controls the oscillator. The frequency controller includes an extracting circuit and an integrating circuit. The extracting circuit extracts a phase change based on the frequency error derived from the phase correction signal of the first step and from a signal preceding that signal by a predetermined delay time. The integrating circuit integrates the phase change and outputs the integrated result as the control signal. The predetermined delay time is preferably set within a range not exceeding the delay time needed for averaging by an averaging circuit that receives the phase correction signal of the first step and outputs a phase correction signal. The carrier to a radio frequency quadrature modulator is preferably supplied from the voltage-controlled oscillator.
