    摘要： A transmitting apparatus which can suppress unnecessary power consumption. An optimal signal line is selected from a plurality of signal lines (53-56) having different gains provided by respective signal amplifying devices to perform gain adjustment on a signal to be transmitted, which is supplied to an input terminal (58), so as to optimize power consumption of each signal amplifying device in accordance with a gain value, and to halt the operation of the signal amplifying device on a signal line which is not selected. Therefore, unnecessary power consumption can be suppressed.

    摘要： A spread spectrum communication system for performing spread spectrum communication by superimposing a pseudo noise signal on a transmitted signal. The system comprises traffic detecting means for detecting the traffic of the transmitted signal, and means for changing the clock frequency of the pseudo noise signal in accordance with the output from the traffic detecting means. The system may alternatively comprise transmission quality determining means for determining the transmission quality of the received signal, and means for changing the clock frequency of the pseudo noise signal in accordance with the transmission quality determined by the transmission quality determining means. In operation, the system offers improved S/N ratios where traffic is high or transmission quality is low, saves power where traffic is low or transmission quality is high, and ensures large margins of power control precision for mobile stations near the upper limit of the system's line capacity.

    摘要： A transmitting apparatus sequentially transmits a wireless packet PK1 for data streaming transmission with a non-transmission period therebetween to a receiving apparatus. A predetermined proportion of non-transmission periods are assigned to a period for transmitting a wireless packet PK2 for control information transmission from the information receiving apparatus to the information transmitting apparatus. The wireless packets PK1, PK2 contain time-position information indicating a second non-transmission period that is not assigned to the transmission from the receiving apparatus to the transmitting apparatus. The receiving apparatus and another transmitting apparatus different from the transmitting apparatus transmitting the wireless packet PK1 can identify the time position of the second non-transmission period by the time-position information contained in the wireless packets PK1, PK2, and can communicate to each other during the second non-transmission period.

    摘要： A scrambling initial value is shared without deteriorating transmission efficiency.On the transmission side, a scrambling initial value is created based on a part of a physical layer header not scrambled, a transmission signal sequence scrambled is created by calculating an exclusive-OR operation between a scrambled sequence generated from the scrambling initial value and a transmission data sequence, and is transmitted. On the reception side, the same descrambling initial value as the scrambling initial value is created based on a part of a physical header of a reception frame, and a reception data sequence is descrambled by calculating an exclusive-OR operation between a descrambled sequence generated from this descrambling initial value and a reception signal sequence scrambled.
