    • A code division multiple access (CDMA) mobile communication system with improvements to permit stable reception with a minimum of bit error. The system includes a base station and a mobile station for communicating with the base station. The mobile station includes an oscillator, a radio frequency demodulator for demodulating a radio frequency band signal received from the base station by use of a first signal from the oscillator, a radio frequency modulator for modulating a second signal to be transmitted by use of the first signal from the oscillator, and an antenna for receiving the radio frequency band signal transmitted from the base station, and for transmitting the modulated second signal to the base station. An oscillation frequency of the oscillator is controlled by use of a change of phase shift detected using the demodulated radio frequency band signal received from the base station.
    • 具有改进的码分多址(CDMA)移动通信系统,以允许以最小的位错误的稳定的接收。 该系统包括用于与基站通信的基站和移动站。 移动台包括振荡器,用于通过使用来自振荡器的第一信号来解调从基站接收的无线电频带信号的射频解调器,用于通过使用第一信号调制要发送的第二信号的射频调制器 来自振荡器的信号,以及用于接收从基站发送的射频信号的天线,并用于将调制的第二信号发送到基站。 通过使用从基站接收的解调的无线电频带信号检测到的相移的变化来控制振荡器的振荡频率。

    • In order to accomplish efficient communication of data between a base station and a plurality of mobile terminals, particular orthogonal codes are transmitted from the mobile stations to the base station as alert signals indicating the presence of data to be transmitted. The base station checks whether particular orthogonal codes are contained in the alert signals, and when the particular orthogonal codes are detected in the alert signals, information representing the detected orthogonal codes and the schedules for transmitting the data from the mobile terminals to the base station are transmitted from the base station to the mobile terminals as an alert response to the alert signals. When the information representing the orthogonal codes used for the alert signals are contained in the alert response transmitted from the base station to the mobile terminals, the data waiting to be transmitted is transmitted from the mobile terminals to the base station according the data transmission schedules in the alert response.
    • 为了在基站和多个移动终端之间实现数据的有效通信,将特定的正交码从移动台发送到基站,作为指示要发送的数据的存在的警报信号。 基站检查警报信号中是否包含特定正交码,并且当在警报信号中检测到特定的正交码时,表示检测到的正交码的信息和用于从移动终端向基站发送数据的时间表是 从基站发送到移动终端作为对警报信号的警报响应。 当表示用于警报信号的正交码的信息被包含在从基站发送到移动终端的警报响应中时,等待发送的数据根据​​数据传输时间表从移动终端发送到基站 警报响应。
