<p><P>PROBLEM TO BE SOLVED: To provide a transmitter easily providing spread communication by an impulse radio communication. <P>SOLUTION: The transmitter 10 for transmitting data by spread spectrum communication has a configuration having: a spread modulation unit 14 for spreading transmission data by spread codes, an RZ converting unit 15 for converting a spread signal into an RZ signal; and an impulse sequence converting unit 16 for multiplying product the RZ signal by the impulse sequence to convert the RZ signal into an impulse radio signal. As described above, since the transmission data are converted into the RZ signal after spreading the data and converted into the impulse radio signal, even if the same value continues in the data, a receiver side can correctly taken out the data, and transmission/reception by the impulse signal is realized. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
