<P>PROBLEM TO BE SOLVED: To suppress an increase of buses of a CDMA type data transmission device in number even when multiplicity is made large. <P>SOLUTION: The data transmission device 10 being a CDMA type data transmission device which multiplexes transmitted data with predetermined multiplicity, includes: an input acceptance section 11 which accepts the input of a plurality of transmitted data; a spread signal generation section which generates spread signals by multiplying the plurality of accepted transmitted data by a previously held spread code series; an addition section 13 which sums up the plurality of generated spread signals according to the multiplicity; and an output section 14 which outputs added values as a digital signal by bits of the digital signal to the buses 20 of the number corresponding to the multiplicity. <P>COPYRIGHT: (C)2007,JPO&INPIT |
