  • Weighted random selection of transmission resources based on device position
    Patent number: 9826431
    Abstract: A transmission method including: a spreading code channel selection for selecting randomly a spreading code channel for CDMA spreading of transmission data, a time slot channel selection for selecting randomly a time slot channel for transmitting the CDMA-spread transmission data, a frequency channel selection for selecting randomly a frequency channel for transmitting the CMDA-spread transmission data, and a transmission for transmitting the transmission data CDMA-spread in the spreading code channel selected in the spreading code channel selection, using the time slot channel selected in the time slot channel selection, at a frequency corresponding to the frequency channel selected in the frequency channel selection.
    Type: Grant

  • Communication system, communication terminal, communication method, chip clock generation method, and orthogonal code generation method
    Patent number: 9184828
    Abstract: When multiple communication terminals access a base station in CDMA in which transmission signals are spread with orthogonal codes, the orthogonal codes in CDMA signals transmitted from the communication terminals are synchronized on the communication path. The communication terminals each include an information acquirer acquiring reference time information common to the multiple communication terminals, a transmission time generator generating a chip clock on the basis of the time information, an orthogonal code generator generating orthogonal codes in time with the timing of the chip clock, a CDMA spreader spreading transmission signals with the orthogonal codes to generate code division multiple access signals, a carrier wave generator generating a carrier wave, and a BPSK modulator modulating the carrier wave generated by the carrier wave generator with the code division multiple access signals and transmitting the carrier wave.
