1. an application code divides transmission simultaneously to relate to the communication equipment of two channel datas, it is characterized in that comprising:

  • The first spread spectrum device (47) is used the first spread-spectrum codes (C I) data that relate to first passage (DTCH) are carried out spread spectrum;

    The second spread spectrum device (50) is used the second spread-spectrum codes (C Q) carry out spread spectrum to relating to the said data of first passage (DTCH);

    The third spread spectrum device (49) is used the said first spread-spectrum codes (C I) data that relate to second channel (PCCH) are carried out spread spectrum;

    The 4th spread spectrum device (48) is used said second kind of spread-spectrum codes (C Q) carry out spread spectrum to relating to the said data of second channel (PCCH);

    With respect to the device (42,55,56) that changes the power level of behind spread spectrum, representing second channel (PCCH) data-signal at the power level of representing first passage (DTCH) data-signal behind the spread spectrum;

    Made the spread spectrum data establishment combination of transmission signals device (57,58,59,60,61,62,63) of the second channel that changes from the spread spectrum data that relates to first passage and power level.
