1. one kind is used for the application code branch sends the data that will transmit simultaneously on two passages communication equipment, it is characterized in that this communication equipment comprises:

  • First expanding unit (47) is used to use the first extended code (C I) data that will transmit on first passage are expanded;

    Second expanding unit (50) is used to use the second extended code (C Q) to expanding in the data of the transmission of first passage;

    The 3rd expanding unit (49) is used to use the described first extended code (C I) data that will transmit on second channel are expanded;

    The 4th expanding unit (48) is used to use the described second extended code (C Q) data that will transmit on second channel are expanded;

    The power level modifier is used for changing the power level of representative at the signal of the data that will transmit after the expansion with respect to the power level of representative at the signal of the data that will transmit after the expansion on second channel on first passage;

    WithComposite set (57,58,59,60,61,62,63) is used for from sending the growth data and reformed will the establishment at the growth data that second channel transmits of its power level of first passage;

    Wherein said composite set comprises;

    First adding device (57), be used to calculate utilize first extended code expansion will the data that transmit on the first passage with utilize the poor of expansion of second extended code and the reformed data that will on second channel, transmit of its power level;

    WithSecond adding device (58), be used to calculate utilize second extended code expansion will the data that transmit on the first passage with utilize expansion of first extended code and the reformed data sum that will on second channel, transmit of its power level.
