    • An encoder encodes sound data and the like to generate a binary signal. A mapper converts the binary signal into a four-level symbol and outputs the four-level symbol. A base band filter includes a root raised cosine filter and a sinc filter. The base band filter blocks a predetermined frequency component of a symbol to shape the symbol into a waveform signal and outputs the waveform signal shaped. An FM modulator transmits a signal subjected to FM modulation according to a magnitude of an amplitude of a waveform signal to a receiving unit. When a symbol of ±3 is outputted from the mapper, a frequency shift of a signal transmitted from the FM modulator has a predetermined value in a range of ±0.822[kHz] to ±0.952[kHz]. This makes it possible to provide a modulating apparatus, a mobile communication system, a modulating method, and a communication method that use a modulating method that can conform to the FCC rule to be enforced in 2005 without using a linear power amplifier.
    • 编码器对声音数据等进行编码以产生二进制信号。 映射器将二进制信号转换为四电平符号并输出四电平符号。 基带滤波器包括根升余弦滤波器和正弦滤波器。 基带滤波器阻挡符号的预定频率分量以将符号形成波形信号,并输出成形的波形信号。 FM调制器根据波形信号的幅度的大小向接收单元发送经受FM调制的信号。 当从映射器输出±3的符号时,从FM调制器发送的信号的频移在±0.822 [kHz]至±0.952 [kHz]的范围内具有预定值。 这使得可以提供一种调制装置,移动通信系统,调制方法和通信方法,该调制方法和通信方法使用可以符合FCC规则的调制方法,以便在2005年不使用线性功率放大器。

    • Information, which has a frame structure and is to be transmitted from a line control apparatus (101) through a control channel to a mobile transmitting/receiving apparatus (102), includes function channel identifying information indicative of the type of information transmitted in an area of control information. When no message is existent which must be notified to the mobile transmitting/receiving apparatus (102), the line control apparatus (101) establishes an idle message in the area of control information and also establishes the function channel identifying information, which is in the same frame, as idle identifying information. If the function channel identifying information is the idle identifying information, the mobile transmitting/receiving apparatus (102) switches a receiving operation in the area of control information into a reception stop operation. Otherwise, the mobile transmitting/receiving apparatus (102) continues the receiving operation in the area of control information. The present invention can start a call in a short time and elongate the operational time with a wireless communication apparatus serving as a mobile wireless station.
    • 具有帧结构并且要从线路控制装置(101)通过控制信道发送到移动发送/接收装置(102)的信息包括指示在区域中发送的信息的类型的功能信道识别信息 的控制信息。 当不存在必须通知移动发送/接收装置(102)的消息时,线路控制装置(101)在控制信息的区域中建立空闲消息,并且建立功能信道识别信息 相同的帧,作为空闲识别信息。 如果功能信道识别信息是空闲识别信息,则移动发送/接收装置(102)将控制信息区域中的接收操作切换为接收停止操作。 否则,移动发送/接收设备(102)在控制信息的区域中继续接收操作。 本发明可以在短时间内开始呼叫并且利用用作移动无线站的无线通信装置来延长操作时间。
