    • In a mobile communication system which uses a code division multiple access (CDMA) scheme for communications between a base station and a plurality of mobile stations, the base station has a transmitting device in which a plurality of information sequences S1 through Sn are respectively spread by multipliers 11 through 1n with a common spreading code from a spreading code generator circuit 10, the spread codes are provided to transmitting timing control circuits 21 through 2n and then added by an adder 30 to perform transmitting timing offset multiplexing and then the spread signals are transmitted to the mobile stations at different transmitting timing. The mobile stations each have a receiving device which receives that one of the transmitted signals which was transmitted at timing predetermined for the mobile station and despreads the received signal with the same spreading code as that used in the transmitting device, thereby reconstructing the original information sequence concerned.

    • The communication system includes: first terminal devices connected to a transmission path and having terminal information; a second terminal device connected to the path and sending an information request requesting the information from the first terminal device; a first superimposing apparatus interposed between the first terminal device and the path; and a second superimposing apparatus interposed between the second terminal device and the path and receiving the request from the second terminal device. The first superimposing apparatus acquires the information from the connected first terminal device at predetermined timings and stores it. Upon receiving the request, the second superimposing apparatus sends the request to the first superimposing apparatus using a superimposed signal superimposed on a transmission signal transmitted via the path. Upon receiving the request, the first superimposing apparatus sends the information to the second superimposing apparatus using the superimposed signal. Upon receiving the information, the second superimposing apparatus provides the information to the second terminal device.

    • A signal transceiving section transmits a transmission signal to a transmission path, each frame in the transmission signal is divided into a plurality of periods in a time axis direction, and the plurality of periods includes superimposing period for superimposing a superimposed signal. A transmission unit includes a signal adjustment section for changing the proportion of the superimposing period in one frame of the transmission signal. The signal adjustment section adjusts the proportion of the superimposing period in accordance with a transmission state of the superimposed signal transmitted between second communication terminals. The signal adjustment section may adjust the proportion of the superimposing period so that the proportion of the superimposing period in one frame of the transmission signal increase with increasing the volume of transmission data transmitted between the second communication terminals through the superimposed signal.
    • 信号收发部将发送信号发送到发送路径,将发送信号中的每个帧在时间轴方向上分割为多个周期,多个周期包括用于叠加叠加信号的叠加期间。 发送单元包括用于改变发送信号的一帧中的叠加周期的比例的信号调整部。 信号调整部根据第二通信终端之间发送的叠加信号的发送状态来调整重叠期间的比例。 信号调整部分可以调整叠加周期的比例,使得传输信号的一帧中的叠加周期的比例随着通过叠加信号的增加在第二通信终端之间传输的传输数据的数量而增加。
